GLXIMPORTCONTEXTEXT()							    GLXIMPORTCONTEXTEXT()

NAME
       glXImportContextEXT - import another process's indirect rendering context.

C SPECIFICATION
       GLXContext glXImportContextEXT( Display *dpy,
				       GLXContextID contextID )

       delim $$

PARAMETERS
       dpy	  Specifies the connection to the X server.

       contextID  Specifies a GLX rendering context.

DESCRIPTION
       glXImportContextEXT  creates a GLXContext given the XID of an existing GLXContext.  It may
       be used in place of glXCreateContext, to share another process's indirect  rendering  con-
       text.

       Only  the  server-side  context	information  can be shared between X clients; client-side
       state, such as pixel storage modes, cannot be shared. Thus, glXImportContextEXT must allo-
       cate  memory to store client-side information. This memory is freed by calling glXFreeCon-
       textEXT.

       This call does not create a new XID.  It merely makes an existing object available to  the
       importing  client  (Display *).	Like any XID, it goes away when the creating client drops
       its connection or the ID is explicitly deleted. Note that this is when the XID goes  away.
       The object goes away when the XID goes away AND the context is not current to any thread.

       If  contextID  refers  to a direct rendering context then no error is generated but glXIm-
       portContextEXT returns NULL.

       glXImportContextEXT 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 glXQueryEx-
       tensionsString, when called with argument GLX_EXTENSIONS, extension EXT_import_context  is
       supported.

ERRORS
       GLXBadContext is generated if contextID does not refer to a valid context.
