FileCatalyst Fast File Transfers - C++ Library
fc Namespace Reference

All of the FileCatalyst classes and objects are declared within the fc namespace. More...

Namespaces

 Logging
 The fc::Logging namespace contains helper functions to easily manage the different types of logging available in FC++.
 
 SummaryLog
 The SummaryLog namespace contains helper functions for generating a summary of what happens within FC++.
 

Classes

class  Control
 fc::Control is the client class C++ API used to control a FTP server and manage file transfers. More...
 
class  Exception
 fc::Exception objects represent a C++ exception and usually includes stack traces and optional parameters to describe the internal state of FC++ at the time the exception happened. More...
 
struct  FileDetails
 A collection of file or directory properties returned when a directory listing has been requested. More...
 
class  GlobalStateAndStats
 Combine both state and statistics into a single class which callers can access. More...
 
class  GlobalStats
 GlobalStats is used to track some summary statistics during file transfers. More...
 
class  Local
 The class fc::Local is used to encapsulate local directories or files. More...
 
class  Name
 To prevent mixing up local path and remote path parameters when calling the FC++ API, the path and/or filenames are wrapped using the simple fc::Local and fc::Remote classes. More...
 
class  Options
 fc::Options contains all the default and user-defined settings required by fc::Control to connect to FTP servers. More...
 
class  Remote
 The class fc::Remote is used to encapsulate remote directories or files. More...
 
class  TransferStats
 File transfer statistics. More...
 

Typedefs

typedef std::map< size_t, fc::TransferStatsTransferStatsMap
 Track all of the individual file transfers, where the key is a numeric sequence describing the order of the file transfer. More...
 
typedef void(* StatisticsCallback) (const fc::GlobalStateAndStats &stats, void *ptr)
 Allow a single callback to be specified when the statistics are updated. More...
 
typedef std::vector< std::string > StrVec
 Defined for convenience: a vector of text strings. More...
 
typedef std::map< std::string, std::string > StrMap
 Defined for convenience: an ordered map where both the key and the value are text strings. More...
 
typedef std::set< std::string > StrSet
 Defined for convenience: an ordered set of text strings. More...
 
typedef std::vector< FileDetailsFDVec
 A std::vector of fc::FileDetails. More...

Detailed Description

All of the FileCatalyst classes and objects are declared within the fc namespace.

Typedef Documentation

typedef std::map<size_t, fc::TransferStats> fc::TransferStatsMap

Track all of the individual file transfers, where the key is a numeric sequence describing the order of the file transfer.

typedef void(* fc::StatisticsCallback) (const fc::GlobalStateAndStats &stats, void *ptr)

Allow a single callback to be specified when the statistics are updated.

During active file transfers, most of the file statistics and global statistics are updated exactly once per second. A callback can be defined which will be called every second immediately after these statistics have been updated.

Warning
This callback interrupts the active file transfer! The file transfer is effectively "paused" while the callback is executing. To prevent negatively affecting the throughput, or causing the transfer to abort, the callback should locally copy the statistics it expects to use and immediately return to ensure the transfer can proceed.

This will normally be used as follows:

static fc::TransferStats singleFileStats;
void myFileTransferStatsCallback( const fc::GlobalStateAndStats &stats, void *ptr )
{
// copy only the current file stats we need and ignore the rest
singleFileStats = stats.fileStatsMap[ stats.fileStatsIdx ];
// signal another app thread to indicate new statistics have been received
...
// quickly return execution control to FC++ to complete the transfer
return;
}
fc::Control control;
control.setStatsCallback( myFileTransferStatsCallback, NULL );
...
typedef std::vector<std::string> fc::StrVec

Defined for convenience: a vector of text strings.

typedef std::map<std::string, std::string> fc::StrMap

Defined for convenience: an ordered map where both the key and the value are text strings.

typedef std::set<std::string> fc::StrSet

Defined for convenience: an ordered set of text strings.

typedef std::vector<FileDetails> fc::FDVec

Enumerations for several common bandwidth values.

Warning
Several of the higher-bps values require more than 32 bits. Meaning this code wont work as expected:
// Problem: In this next line, the value for 10 Gbps will be truncated
// or cause a compiler warning if "int" is only 32 bits wide.
int my_bps = fc::k10_Gbps;
...
options.setBandwidth( my_bps );
Instead, you'll want to pass the enum directly, or use a 64-bit unsigned integer for bps values:
uint64_t my_bps = fc::k10_Gbps; // no truncation
options.setBandwidth( my_bps ); // this will work correctly
// this would also work:
my_bps = fc::bps( fc::k10_Gbps );
options.setBandwidth( my_bps );
// these three would also work correctly:
options.setBandwidth( 10000000000 );
options.setBandwidth( fc::Gbps(10) );

An enum to represent possible FTP server reply code.

  • Reply codes 100+ means the requested action is being taken. Expect another reply before proceeding with a new command.
  • Reply codes 200+ means the requested action has been successfully completed.
  • Reply codes 300+ means the command has been accepted, but the requested action is being held pending receipt of further information.
  • Reply codes 400+ means the command was not accepted and the requested action did not take place. The error condition may be temporary.
  • Reply codes 500+ means the command was not accepted and the requested action did not take place.
  • Negative values are used in the enum to represent pseudo-responses. These are handled not by directly matching server response codes, but through logic or through range checking. None of these values are for direct public use, nor are they exposed externally by any parts of the FC++ library.

uint64_t fc::bps ( const fc::ECommonBandwidth bandwidth)

Convert the common bandwidth enum value to a usable bps value.

See also
fc::formatTransferRate() to convert bps to a string.
fc::Kbps()
fc::Mbps()
fc::Gbps()
Warning
Some of the high bandwidth values cannot be represented using a 31-bit int, or a 32-bit uint. You must use uint64_t to store bps.
uint64_t bps = fc::bps( fc::k10_Mbps );
bps *= 3;
std::cout << fc::formatTransferRate( bps ) << std::endl;
// this should output "30.00 Mbps"

std::string fc::formatTransferStatsEState ( const fc::TransferStats::EState  state)
time_t fc::to_time_t ( const std::chrono::high_resolution_clock::time_point &  tp)

Convenience function to convert time_point objects to traditional time_t values (seconds since 1970-01-01 00:00:00 UTC).

Returns
Once converted, the time_t values can used with legacy 'C' APIs. If the time point object isn't a valid timestamp, then a value of zero is returned.

Here is the caller graph for this function:

std::string fc::formatTimeRecent ( const std::chrono::high_resolution_clock::time_point &  tp)

Format the time in an easy-to-read text string.

The specified time can be in the past or in the future. The further from now, the more precision will be sacrificed for ease of readability.

fc::Control ftp( ... );
...
const fc::TransferStats &stats = ftp.getMostRecentFileStats();
std::cout << fc::formatTimeRecent(stats.timeTransferFinished) << std::endl;

For example, the text returned could be:

  • "in 3 hours"
  • "10 minutes ago"
  • "in 45 seconds"
Returns
"unknown" if the timepoint is invalid

References to_time_t().

Here is the call graph for this function:

Here is the caller graph for this function:

std::string fc::formatTimeRecent ( const time_t  tt)

Format the absolute time in an easy-to-read text string.

The specified time can be in the past or in the future. The further from now, the more precision will be sacrificed for ease of readability.

time_t tt = time(nullptr) - 10800;
std::cout << fc::formatTimeRecent(tt) << std::endl;
// should result in the text string "3 hours ago"

For example, the text returned could be:

  • "in 3 hours"
  • "10 minutes ago"
  • "in 45 seconds"
Parameters
[in]ttThe time "tt" is absolute (not relative) meaning it must contain the number of seconds since 1970-01-01 0:00:00.
Returns
"unknown" if the time is more than 10 days ago, or more than 10 days from now.
std::string fc::formatTimeDuration ( const std::chrono::high_resolution_clock::duration &  d)

Format the "time remaining" statistic as a number followed by a common 1-letter description.

fc::Control ftp( ... );
...
const fc::TransferStats &stats = ftp.getMostRecentFileStats();
std::cout << fc::formatTimeDuration(stats.timeRemaining) << std::endl;

For example, the text returned could be:

  • 10s
  • 45m
  • 3h

Here is the caller graph for this function:

std::string fc::formatTimeDuration ( const time_t  tt)

Format the relative "time remaining" statistic as a number followed by a common 1-letter description.

time_t tt = 420; // seconds
std::cout << fc::formatTimeDuration(tt) << std::endl;
// should result in the text string "7m"

For example, the text returned could be:

  • 10s
  • 45m
  • 3h
Parameters
[in]ttThe time "tt" is relative (not absolute) meaning it is relative to now, not since epoch (1970-01-01 0:00:00).
std::string fc::formatTimeDuration2 ( const std::chrono::high_resolution_clock::duration &  d)

Format the "time remaining" statistic as a common time string, such as HH:MM:SS.

If HH is zero, then only MM:SS will be returned.

fc::Control ftp( ... );
...
const fc::TransferStats &stats = ftp.getMostRecentFileStats();
std::cout << fc::formatTimeDuration2(stats.timeRemaining) << std::endl;

For example, the text returned could be:

  • 0:10
  • 3:00:18

Here is the caller graph for this function:

std::string fc::formatTimeDuration2 ( const time_t  tt)

Format the relative "time remaining" statistic as a common time string, such as HH:MM:SS.

If HH is zero, then only MM:SS will be returned.

time_t tt = 432; // seconds
std::cout << fc::formatTimeDuration2(tt) << std::endl;
// should result in the text string "7:12"

For example, the text returned could be:

  • 0:10
  • 3:00:18
Parameters
[in]ttThe time "tt" is relative (not absolute) meaning it is relative to now, not since epoch (1970-01-01 0:00:00).
std::string fc::formatTimestamp ( const std::chrono::high_resolution_clock::time_point &  tp)

Format the absolute time point using "YYYY:MM:DD HH:MM:SS".

fc::Control ftp( ... );
...
const fc::TransferStats &stats = ftp.getMostRecentFileStats();
std::cout << fc::formatTimestamp(stats.timeTransferBegan) << std::endl;

For example, the text returned could be:

  • 2014-09-17 08:53:16

References to_time_t().

Here is the call graph for this function:

Here is the caller graph for this function:

std::string fc::formatTimestamp2 ( const std::chrono::high_resolution_clock::time_point &  tp)

Format the absolute time point using "YYYY:MM:DD HH:MM:SS.mmmmmm" where mmmmmm is microseconds.

Reminder:

  • 1 second == 1,000 milliseconds
  • 1 second == 1,000,000 microseconds
  • 1 second == 1,000,000,000 nanoseconds

So a valid microsecond value ranges from 0 to 999,999.

const fc::StrMap & fc::emptyMap ( void  )

Function that always returns an empty map. Used internally by FC++.

std::string fc::baseVersionStr ( void  )

Return a simple version string.

This is the base version of the FileCatalyst software, not the FC++ library version. This should be similar to:

  • "2.8.0"
  • "3.0.0"
  • "3.0.1"
