Detailed Description

Private namespace for libpqxx's internal use; do not access.

This namespace hides definitions internal to libpqxx. These are not supposed to be used by client programs, and they may change at any time without notice.

Conversely, if you find something in this namespace tremendously useful, by all means do lodge a request for its publication.

Warning: Here be dragons!

	)		throw ()

Human-readable description for error code, possibly using given buffer.

Wrapper for strerror() or thread-safe variant, as available. The default code copies the string to the provided buffer, but this may not always be necessary. The result is guaranteed to remain usable for as long as the given buffer does.

Parameters

err	system error code as copied from errno
buf	caller-provided buffer for message to be stored in, if needed
len	usable size (in bytes) of provided buffer

Returns: human-readable error string, which may or may not reside in buf

Throw exception for attempt to convert null to given type.

Referenced by pqxx::string_traits< PGSTD::string >::null(), pqxx::string_traits< const PGSTD::string >::null(), and pqxx::string_traits< PGSTD::stringstream >::null().
