glXGetContextIDEXT.3G - Man Page
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 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.
