◆ intf_InsertItem()

int intf_InsertItem ( libvlc_int_t libvlc,
const char *  mrl,
unsigned  optc,
const char *const *  optv,
unsigned  flags 
)

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,
const char *  psz_option,

)

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_objthe object in which the variable must be created
psz_optionthe option to parse
trustedwhether 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_thisan existing VLC object
i_sizebyte size of the object structure
psz_typeobject type name
Returns
the created object, or NULL.

◆ vlc_ExitInit()

void vlc_ExitInit ( vlc_exit_t )

◆ vlc_LogInit()

void vlc_LogInit ( libvlc_int_t )

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.

void *  cbs_userdata,
int  timeout,

)

◆ vlc_object_deinit()

void vlc_object_deinit ( vlc_object_t obj)

Deinitializes a VLC object.

This frees resources allocated by vlc_object_init().

References vlc_object_internals::resources, var_DestroyAll(), vlc_internals, vlc_restorecancel(), and vlc_savecancel().

Referenced by vlc_object_delete().

◆ vlc_object_init()

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

Initializes a VLC object.

Parameters
objstorage space for object to initialize [OUT]
parentparent object (or NULL to initialize the root) [IN]
type_nameobject 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
0on success
-1on (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
objobject whose resources to release

◆ vlc_objres_new()

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

Allocates an object resource.

Parameters
sizestorage size in bytes of the resource data
releasecallback 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
objobject to allocate the resource for
dataresource 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
objobject whose resource to release
dataprivate data for the comparison function
matchcomparison function to match the targeted resource
