Function Documentation

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.

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.

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.

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.

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.
