module_list_cap()

ssize_t module_list_cap	(	module_t ***restrict	list,
		const char *	name
	)

Builds a sorted list of all VLC modules with a given capability.

The list is sorted from the highest module score to the lowest.

Parameters

list	pointer to the table of modules [OUT]
name	name of capability of modules to look for

Returns

the number of matching found, or -1 on error (*list is then NULL).

Note

*list must be freed with module_list_free().

module_list_free()

void module_list_free

(

module_t **

list

)

Frees the flat list of VLC modules.

Parameters

list	list obtained by module_list_get()
length	number of items on the list

Returns

nothing.

module_list_get()

module_t** module_list_get

(

size_t *

n

)

Gets the flat list of VLC modules.

Parameters

n	[OUT] pointer to the number of modules

Returns

table of module pointers (release with module_list_free()), or NULL in case of error (in that case, *n is zeroed).

module_LoadPlugins()

void module_LoadPlugins

(

Loads module descriptions for all available plugins.

Fills the module bank structure with the plugin modules.
