man ggiOpen (Fonctions bibliothèques) - ggiOpen, ggiClose : Open and close a visual
NAME
ggiOpen, ggiClose : Open and close a visual
SYNOPSIS
#include <ggi/ggi.h>
ggi_visual_t ggiOpen(const char *display, ...);
int ggiClose(ggi_visual_t vis);
DESCRIPTION
ggiOpen opens a visual. The visual is specified as a display string, followed by NULL. If only NULL is specified, the default display target is opened. The other arguments are for internal purposes only, such as argptr, used to pass driver-specific, non-textual information to the driver.
ggiClose releases and destroys an open visual. This will close X windows, return consoles to text-mode, etc.
RETURN VALUE
ggiOpen returns the opened visual or NULL for error. The ggi_visual_t is opaque to the programmer and should only be used through GGI functions.
ggiClose returns 0 for OK, otherwise an error code.
EXAMPLES
Open and closing default visual:
ggi_visual_t vis = ggiOpen(N);
if(vis==NULL) { ggiPanic("Couldn't open default visual!\n"); }
/* do stuff */
ggiClose(vis);
Open and closing a memory visual:
ggi_visual_t memvis = ggiOpen("display-memory", NULL);
if(memvis==NULL) { return -1; }
/* do stuff */
ggiClose(memvis);
