NAME
glXQueryContext - query context information
C SPECIFICATION
int glXQueryContext(Display * dpy, GLXContext ctx, int attribute, int * value);
PARAMETERS
dpy Specifies the connection to the X server. ctx Specifies a GLX rendering context. attribute Specifies that a context parameter should be retrieved. Must be one of GLX_FBCONFIG_ID, GLX_RENDER_TYPE, or GLX_SCREEN. value Contains the return value for attribute.
DESCRIPTION
glXQueryContext sets value to the value of attribute with respect to ctx. attribute may be one of the following: GLX_FBCONFIG_ID Returns the XID of the GLXFBConfig associated with ctx. GLX_RENDER_TYPE Returns the rendering type supported by ctx. GLX_SCREEN Returns the screen number associated with ctx. Success is returned unless attribute is not a valid GLX context attribute, in which case GLX_BAD_ATTRIBUTE is returned. This call may cause a round-trip to the server.
NOTES
glXQueryContext is available only if the GLX version is 1.3 or greater. If the GLX version is 1.1 or 1.0, the GL version must be 1.0. If the GLX version is 1.2, then the GL version must be 1.1. If the GLX version is 1.3, then the GL version must be 1.2.
ERRORS
GLXBadContext is generated if ctx does not refer to a valid context.
