Function Documentation

◆ module_EndBank()

void module_EndBank ( bool  b_plugins)

◆ module_InitBank()

void module_InitBank ( void  )

Init bank.

Creates a module bank structure which will be filled later on with all the modules found.

Referenced by libvlc_InternalInit().

◆ module_InitStatic()

static vlc_plugin_t* module_InitStatic ( vlc_plugin_cb  entry)
static

Registers a statically-linked plug-in.

◆ 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
listpointer to the table of modules [OUT]
namename 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
listlist obtained by module_list_get()
lengthnumber of items on the list
Returns
nothing.

Referenced by config_ListModules(), ListModules(), module_find(), module_LoadPlugins(), and vlc_module_load().

◆ 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).

Referenced by ListModules(), module_find(), and module_LoadPlugins().

◆ module_LoadPlugins()

size_t module_LoadPlugins ( vlc_object_t obj)

Loads module descriptions for all available plugins.

Fills the module bank structure with the plugin modules.

Parameters
p_thisvlc object structure
Returns
total number of modules in bank after loading all plug-ins
