NAME
ggiOpen, ggiClose - Open and close a visualSYNOPSIS
#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, which means first examining GGI_DISPLAY, then invoking display-auto(7). 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 a ggi-error(3) code.
EXAMPLES
Open and closing default visual:ggi_visual_t vis = ggiOpen(NULL); 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);
