Set or get a mode on a visual

Name

ggiSetMode, ggiGetMode : Set or get a mode on a visual

Synopsis

#include <ggi/ggi.h>

int ggiSetMode(ggi_visual_t visual, ggi_mode *tm);

int ggiGetMode(ggi_visual_t visual, ggi_mode *tm);

Description

ggiSetMode sets any mode (text or graphics). It also performs mode negotiation like ggiCheckMode(3), but if any non-GGI_AUTO/GT_AUTO parameters are changed from the original mode, the new mode will not be silently set.

ggiGetMode fills out the passed ggi_mode(3) with the parameters of the current mode of the visual.

Return value

ggiSetMode returns 0 if the mode is set successfully, otherwise an gg-error(3) code.

Notes

Do not set a mode before checking it. You may be able to set up a certain mode on one target, but not other targets.

See the example in ggiCheckMode(3).
