Inserts an item in the playlist.

This function is used during initialization. It inserts an item to the beginning of the playlist. That is meant to compensate for the reverse parsing order of the command line.

var_OptionParse()

void var_OptionParse	(	vlc_object_t *	p_obj,

Parse a stringified option This function parse a string option and create the associated object variable The option must be of the form "[no[-]]foo[=bar]" where foo is the option name and bar is the value of the option.

Parameters

p_obj	the object in which the variable must be created
psz_option	the option to parse
trusted	whether the option is set by a trusted input or not

Returns

nothing

vlc_custom_create()

void * vlc_custom_create	(	vlc_object_t *	p_this,
		size_t	i_size,
		const char *	psz_type
	)

Creates a VLC object.

Note that because the object name pointer must remain valid, potentially even after the destruction of the object (through the message queues), this function CANNOT be exported to plugins as is. In this case, the old vlc_object_create() must be used instead.

Parameters

p_this	an existing VLC object
i_size	byte size of the object structure
psz_type	object type name

Returns

the created object, or NULL.

vlc_LogInit()

void vlc_LogInit

(

)

Initializes the messages logging subsystem and drain the early messages to the configured log.

References discard_log, vlc_object_t::logger, libvlc_int_t::obj, vlc_LogModuleCreate(), vlc_LogSwitch(), and VLC_OBJECT.

Referenced by libvlc_InternalInit().

vlc_LogPreinit()

int vlc_LogPreinit

(

libvlc_int_t *

vlc

)

Performs preinitialization of the messages logging subsystem.

Early log messages will be stored in memory until the subsystem is fully initialized with vlc_LogInit(). This enables logging before the configuration and modules bank are ready.

Returns

0 on success, -1 on error.

vlc_object_deinit()

void vlc_object_deinit

(

vlc_object_t *

obj

)

Deinitializes a VLC object.

This frees resources allocated by vlc_object_init().

vlc_object_init()

int vlc_object_init	(	vlc_object_t *	obj,
		vlc_object_t *	parent,
		const char *	type_name
	)

Initializes a VLC object.

Parameters

obj	storage space for object to initialize [OUT]
parent	parent object (or NULL to initialize the root) [IN]
type_name	object type name

Note

The type name pointer must remain valid even after the object is deinitialized, as it might be passed by address to log message queue. Using constant string literals is appropriate.

Return values

0	on success
-1	on (out of memory) error

vlc_objres_clear()

void vlc_objres_clear

(

vlc_object_t *

obj

)

Releases all resources of an object.

All resources added with vlc_objres_add() are released in reverse order. The resource list is reset to empty.

Parameters

obj	object whose resources to release

vlc_objres_new()

void * vlc_objres_new	(	size_t	size,
		void(*)(void *)	release
	)

Allocates an object resource.

Parameters

size	storage size in bytes of the resource data
release	callback to release the resource

Returns

a pointer to the (uninitialized) storage space, or NULL on error

vlc_objres_push()

void vlc_objres_push	(	vlc_object_t *	obj,
		void *	data
	)

Pushes an object resource on the object resources stack.

Parameters

obj	object to allocate the resource for
data	resource base address (as returned by vlc_objres_new())

vlc_objres_remove()

void vlc_objres_remove	(	vlc_object_t *	obj,
		void *	data,
		bool(*)(void *, void *)	match
	)

Releases one object resource explicitly.

If a resource associated with an object needs to be released explicitly earlier than normal, call this function. This is relatively slow and should be avoided.

Parameters

obj	object whose resource to release
data	private data for the comparison function
match	comparison function to match the targeted resource
