glXGetContextIDEXT.3G man page

glXGetContextIDEXT — get the XID for a context.

C Specification

GLXContextID glXGetContextIDEXT(const GLXContext ctx);

Parameters

ctx

Specifies a GLX rendering context.

Description

glXGetContextIDEXT 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 GLX_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(), the extension is supported.

Errors

None is returned if ctx is NULL. Otherwise, if ctx does not refer to a valid context, undefined behavior results.
