Detailed Description

libvlc_log_* functions provide access to the LibVLC messages log.

This is used for debugging or by advanced users.

Typedef Documentation

typedef struct libvlc_log_iterator_t libvlc_log_iterator_t

This structure is opaque.

It represents a libvlc log iterator

typedef struct libvlc_log_message_t libvlc_log_message_t

typedef struct libvlc_log_t libvlc_log_t

This structure is opaque.

It represents a libvlc log instance

)

This function does nothing.

It is only provided for backward compatibility.

Parameters:

p_log

ignored

void libvlc_log_close

(

libvlc_log_t *

p_log

)

Frees memory allocated by libvlc_log_open().

Parameters:

p_log

libvlc log instance or NULL
