glutinitdisplaystring(3) - Linux man page

Name

glutInitDisplayString - Set the window creation display mode.

Library

OpenGLUT - window

Synopsis

#include <openglut.h>

void

glutInitDisplayString(const char *displayMode);

Parameters

displayMode Requested display mode string.

Description

glutInitDisplayString() permits you to define a display mode for subsequent windows that you open. In most regards, control is at least as fine as with glutInitDisplaymode().

The displayMode parameter is case-sensitive, and tokens are separated by ASCII TABs (\t) and SPACEs.

Caveats

Conflicting modes, such as single and double have the same interaction as for glutInitDisplayMode().

Todo

GLUT_BORDERLESS and GLUT_OFFSCREEN are not represented.

Not all features appear to be implemented. In particular, numeric parameters and comparator specifications are lacking. See GLUT 3.7 sources for example.
