ast_pjproject_caching_pool_destroy()

void ast_pjproject_caching_pool_destroy

(

pj_caching_pool *

cp

)

Destroy caching pool factory and all cached pools.

Since

13.21.0

Parameters

cp	Caching pool factory to destroy

void ast_pjproject_caching_pool_init	(	pj_caching_pool *	cp,
		const pj_pool_factory_policy *	policy,
		pj_size_t	max_capacity
	)

Parameters

cp	Caching pool factory to initialize
policy	Pool factory policy
max_capacity	Total capacity to be retained in the cache. Zero disables caching.

ast_pjproject_get_buildopt()

int ast_pjproject_get_buildopt	(	char *	option,
		char *	format_string,

	)

Retrieve a pjproject build option.

Parameters

option	The build option requested
format_string	A scanf-style format string to parse the option value into
