Typedef Documentation

◆ vlc_log_early_t

Early (latched) message log.

A message log that stores messages in memory until another log is available.

◆ vlc_LogCallback()

static void vlc_LogCallback ( vlc_logger_t logger,
int  type,
const vlc_log_t item,

static

◆ vlc_logger_load()

static int vlc_logger_load ( void *  func,
bool  forced,

static

◆ vlc_LogInit()

void vlc_LogInit ( libvlc_int_t vlc)

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

◆ vlc_LogModuleClose()

static void vlc_LogModuleClose ( void *  d)
static

◆ vlc_LogModuleCreate()

static struct vlc_logger* vlc_LogModuleCreate ( vlc_object_t parent)
static

◆ 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.
