XLIB FUNCTIONS                                 XSaveContext(3x11)



NAME
     XSaveContext, XFindContext, XDeleteContext, XUniqueContext -
     associative look-up routines

SYNTAX
     cc [ flag... ] file... -lX11 [ library... ]

     int XSaveContext(Display *display, XID rid, XContext con-
          text, XPointer data);

     int XFindContext(Display *display, XID rid, XContext con-
          text, XPointer *data_return);

     int XDeleteContext(Display *display, XID rid, XContext con-
          text);

     XContext XUniqueContext(void);

ARGUMENTS
     context   Specifies the context type to which the data
               belongs.

     data      Specifies the data to be associated with the win-
               dow and type.

     data_return
               Returns the data.

     display   Specifies the connection to the X server.

     rid       Specifies the resource ID with which the data is
               associated.

DESCRIPTION
     If an entry with the specified resource ID and type already
     exists, XSaveContext overrides it with the specified con-
     text.  The XSaveContext function returns a nonzero error
     code if an error has occurred and zero otherwise.  Possible
     errors are XCNOMEM (out of memory).

     Because it is a return value, the data is a pointer.  The
     XFindContext function returns a nonzero error code if an
     error has occurred and zero otherwise.  Possible errors are
     XCNOENT (context-not-found).

     The XDeleteContext function deletes the entry for the given
     resource ID and type from the data structure.  This function
     returns the same error codes that XFindContext returns if
     called with the same arguments.  XDeleteContext does not
     free the data whose address was saved.

     The XUniqueContext function creates a unique context type
     that may be used in subsequent calls to XSaveContext.
