Detailed Description

Function Documentation

pjsip_media_type_init()

void pjsip_media_type_init	(	pjsip_media_type *	mt,
		pj_str_t *	type,
		pj_str_t *	subtype
	)

Initialize the media type with the specified type and subtype string.

Parameters

mt	The media type.
type	Optionally specify the media type.
subtype	Optionally specify the media subtype.

pjsip_media_type_init2()

void pjsip_media_type_init2	(	pjsip_media_type *	mt,
		char *	type,
		char *	subtype
	)

Initialize the media type with the specified type and subtype string.

Parameters

mt	The media type.
type	Optionally specify the media type.
subtype	Optionally specify the media subtype.

pjsip_media_type_cmp()

int pjsip_media_type_cmp	(	const pjsip_media_type *	mt1,
		const pjsip_media_type *	mt2,
		int	cmp_param
	)

Compare two media types.

Parameters

mt1	The first media type.
mt2	The second media type.
cmp_param	Specify how to compare the media type parameters: 0: do not compare parameters 1: compare parameters but ignore parameters that only appear in one of the media type. 2: compare the parameters.

Returns

Zero if both media types are equal, -1 if mt1 < mt2, 1 if mt1 > mt2.

pjsip_media_type_cp()

void pjsip_media_type_cp	(	pj_pool_t *	pool,
		pjsip_media_type *	dst,
		const pjsip_media_type *	src
	)

Copy SIP media type to another.

Parameters

pool	Pool to duplicate strings.
dst	Destination structure.
src	Source structure.

pjsip_media_type_print()

int pjsip_media_type_print	(	char *	buf,
		unsigned	len,
		const pjsip_media_type *	mt
	)

Print media type to the specified buffer.

Parameters

buf	Destination buffer.
len	Length of the buffer.
mt	The media type to be printed.

Returns

The number of characters printed to the buffer, or -1 if there's not enough space in the buffer.
