glXGetContextIDEXT

get the XID for a context.

Signature

glXGetContextIDEXT( const GLXContext ( ctx ) )-> GLXContextID

Parameters

VariablesDescription
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.
