Detailed Description

Function Documentation

struct nfct_helper* nfct_helper_alloc

(

void

)

nfct_helper_alloc - allocate a new helper object

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

Definition at line 102 of file libnetfilter_cthelper.c.

const void* nfct_helper_attr_get	(	struct nfct_helper *	helper,
		enum nfct_helper_attr_type	type
	)

nfct_helper_attr_get - get one attribute the helper object

Parameters

nfct_helper	pointer to the helper 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.

Definition at line 320 of file libnetfilter_cthelper.c.

const char* nfct_helper_attr_get_str	(	struct nfct_helper *	nfct_helper,
		enum nfct_helper_attr_type	type
	)

nfct_helper_attr_get_str - get one attribute the helper object

Parameters

nfct_helper	pointer to the helper 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.

Definition at line 372 of file libnetfilter_cthelper.c.

uint16_t nfct_helper_attr_get_u16	(	struct nfct_helper *	nfct_helper,
		enum nfct_helper_attr_type	type
	)

nfct_helper_attr_get_u16 - get one attribute the helper object

Parameters

nfct_helper	pointer to the helper object
type	attribute type you want to set

This function returns a unsigned 16-bits integer. If the attribute is unsupported, this returns NULL.

Definition at line 402 of file libnetfilter_cthelper.c.

uint32_t nfct_helper_attr_get_u32	(	struct nfct_helper *	nfct_helper,
		enum nfct_helper_attr_type	type
	)

nfct_helper_attr_get_u32 - get one attribute the helper object

Parameters

nfct_helper	pointer to the helper object
type	attribute type you want to set

This function returns a unsigned 32-bits integer. If the attribute is unsupported, this returns NULL.

Definition at line 417 of file libnetfilter_cthelper.c.

uint8_t nfct_helper_attr_get_u8	(	struct nfct_helper *	nfct_helper,
		enum nfct_helper_attr_type	type
	)

nfct_helper_attr_get_u8 - get one attribute the helper object

Parameters

nfct_helper	pointer to the helper object
type	attribute type you want to set

This function returns a unsigned 8-bits integer. If the attribute is unsupported, this returns NULL.

Definition at line 387 of file libnetfilter_cthelper.c.

void nfct_helper_attr_set	(	struct nfct_helper *	h,
		enum nfct_helper_attr_type	type,
		const void *	data
	)

nfct_helper_attr_set - set one attribute of the helper object

Parameters

nfct_helper	pointer to the helper object
type	attribute type you want to set
data	pointer to data that will be used to set this attribute

Definition at line 206 of file libnetfilter_cthelper.c.

		enum nfct_helper_attr_type	type,
		const char *	name
	)

nfct_helper_attr_set_str - set one attribute the helper object

Parameters

type	attribute type you want to set
name	string that will be used to set this attribute

Definition at line 262 of file libnetfilter_cthelper.c.

void nfct_helper_attr_unset	(	struct nfct_helper *	nfct_helper,
		enum nfct_helper_attr_type	type
	)

nfct_helper_attr_unset - unset one attribute the helper object

Parameters
