get_desktop_resolution(3) Allegro manual get_desktop_resolution(3) NAME get_desktop_resolution - Finds out the desktop resolution. Allegro game programming library. SYNOPSIS #include <allegro.h> int get_desktop_resolution(int *width, int *height); DESCRIPTION Finds out the currently selected desktop resolution. You can use this information to avoid creating windows bigger than the current resolu- tion. This is especially important for some windowed drivers which are unable to create windows bigger than the desktop. Each parameter is a pointer to an integer where one dimension of the screen will be stored. Under some OSes, switching to a full screen graphics mode may automati- cally change the desktop resolution. You have, therefore, to call this function before setting any graphics mode in order to retrieve the real desktop resolution. Example: int width, height; allegro_init(); ... if (get_desktop_resolution(&width, &height) == 0) { /* Got the resolution correctly */ } RETURN VALUE Returns zero on success, or a negative number if this information is not available or does not apply, in which case the values stored in the variables you provided for `width' and `height' are undefined.
