Detailed Description

Typedef Documentation

libvlc_dialog_cbs

typedef struct libvlc_dialog_cbs libvlc_dialog_cbs

Dialog callbacks to be implemented.

Attention

starting with vlc 4.0.0 the error callback (pf_display_error) is no longer part of this struct and need to be registered separately using libvlc_dialog_set_error_callback

libvlc_dialog_set_error_callback

libvlc_dialog_error_cbs

typedef void(* libvlc_dialog_error_cbs) (void *p_data, const char *psz_title, const char *psz_text)

Called when an error message needs to be displayed.

Parameters

p_data	opaque pointer for the callback
psz_title	title of the dialog
psz_text	text of the dialog

libvlc_dialog_question_type
