glXGetContextIDEXT()glXGetContextIDEXT()NAMEglXGetContextIDEXT - get the XID for a context.
SYNOPSIS
GLXContextID glXGetContextIDEXT(
const GLXContext ctx );
PARAMETERS
Specifies a GLX rendering context.
DESCRIPTIONglXGetContextIDEXT() returns the XID associated with a GLXContext.
No round trip is forced to the server; unlike most X calls that return
a value, glXGetContextIDEXT() does not flush any pending events.
glXGetContextIDEXT() is part of the EXT_import_context extension, not
part of the core GLX command set. If GLX_EXT_import_context is included
in the string returned by glXQueryExtensionsString(), when called with
argument GLX_EXTENSIONS, extension EXT_import_context is supported.
ERRORS
GLXBadContext is generated if ctx does not refer to a valid context.
