__ast_format_cache_get()

struct ast_format* __ast_format_cache_get	(	const char *	name,
		const char *	tag,
		const char *	file,
		int	line,
		const char *	func
	)

Retrieve a named format from the cache.

Parameters

name	Name of the cached format

Return values

non-NULL	if found
NULL	if not found

Note

The returned format has its reference count incremented. It must be dropped using ao2_ref or ao2_cleanup.

ast_format_cache_get_by_codec()

struct ast_format* ast_format_cache_get_by_codec

(

const struct ast_codec *

codec

)

Retrieve a format from the cache by its codec.

Parameters

codec

The codec to search by

Return values

non-NULL	if found
NULL	if not found

Note

The returned format has its reference count incremented. It must be dropped using ao2_ref or ao2_cleanup.

ast_format_cache_get_slin_by_rate()

struct ast_format* ast_format_cache_get_slin_by_rate

(

unsigned int

rate

)

Retrieve the best signed linear format given a sample rate.

Parameters

rate	The sample rate

This is a convenience function that returns one of the global ast_format_slinxxx formats.

Returns

pointer to the signed linear format

Note

The returned format has NOT had its reference count incremented.
