glXGetContextIDEXT Subroutine

Purpose

Gets the XID for a context

Library

C bindings library: libGL.a

C Syntax

GLXContextID glXGetContextIDEXT(
    const GLXContext ctx) 

Parameters

ctx

Specifies a GLX rendering context.

Description

The glXGetContextIDEXT subroutine 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.

The glXGetContextIDEXT subroutine 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.
