ggiSetMode(3)
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 ggierror(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).
- Important: Note that the ggiSetTextMode(3), ggiSetGraphMode(3) and ggiSetSimpleMode(3) functions are deprecated. Use ggiCheckMode(3) and similar functions, and then use ggiSetMode(3) on the resulting adjusted ggi_mode(3), once you have checked it yourself.
