struct nfacct* nfacct_alloc

(

void

)

nfacct_alloc - allocate a new accounting object

In case of success, this function returns a valid pointer, otherwise NULL s returned and errno is appropriately set.

const void* nfacct_attr_get	(	struct nfacct *	nfacct,
		enum nfacct_attr_type	type
	)

nfacct_attr_get - get one attribute the accounting object

Parameters

nfacct	pointer to the accounting object
type	attribute type you want to set

This function returns a valid pointer to the attribute data. If a unsupported attribute is used, this returns NULL.

References bitset, bytes, flags, name, NFACCT_ATTR_BYTES, NFACCT_ATTR_FLAGS, NFACCT_ATTR_NAME, NFACCT_ATTR_PKTS, NFACCT_ATTR_QUOTA, NULL, pkts, and quota.

const char* nfacct_attr_get_str	(	struct nfacct *	nfacct,
		enum nfacct_attr_type	type
	)

nfacct_attr_get_str - get one attribute the accounting object

Parameters

nfacct	pointer to the accounting object
type	attribute type you want to set

This function returns a valid pointer to the beginning of the string. If the attribute is unsupported, this returns NULL.

uint64_t nfacct_attr_get_u64	(	struct nfacct *	nfacct,
		enum nfacct_attr_type	type
	)

nfacct_attr_get_u64 - get one attribute the accounting object

Parameters

nfacct	pointer to the accounting object
type	attribute type you want to set

This function returns a unsigned 64-bits integer. If the attribute is unsupported, this returns NULL.

Here is the call graph for this function:

void nfacct_attr_set	(	struct nfacct *	nfacct,
		enum nfacct_attr_type	type,
		const void *	data
	)

nfacct_attr_set - set one attribute of the accounting object

Parameters

nfacct	pointer to the accounting object
type	attribute type you want to set
data	pointer to data that will be used to set this attribute

void nfacct_free

(

struct nfacct *

nfacct

)

nfacct_free - release one accounting object

Parameters

nfacct

pointer to the accounting object

int nfacct_snprintf	(	char *	buf,
		size_t	size,
		struct nfacct *	nfacct,
		uint16_t	type,
		uint16_t	flags
	)

nfacct_snprintf - print accounting object into one buffer

Parameters

buf	pointer to buffer that is used to print the object
size	size of the buffer (or remaining room in it).
nfacct	pointer to a valid accounting object.
type	format output type, NFACCT_SNPRINTF_T_[PLAIN|XML]
flags	output flags (NFACCT_SNPRINTF_F_FULL).

This function returns -1 in case that some mandatory attributes are missing. On sucess, it returns 0.
