21 context Specifies the context type to which the data belongs.
22
23 data Specifies the data to be associated with the window and type.
24
25 data_return
26 Returns the data.
27
28 display Specifies the connection to the X server.
29
30 rid Specifies the resource ID with which the data is associated.
31
33 If an entry with the specified resource ID and type already exists,
34 XSaveContext overrides it with the specified context. The XSaveContext
35 function returns a nonzero error code if an error has occurred and zero
36 otherwise. Possible errors are XCNOMEM (out of memory).
37
38 Because it is a return value, the data is a pointer. The XFindContext
39 function returns a nonzero error code if an error has occurred and zero
40 otherwise. Possible errors are XCNOENT (context-not-found).
41
42 The XDeleteContext function deletes the entry for the given resource ID
43 and type from the data structure. This function returns the same error
44 codes that XFindContext returns if called with the same arguments.
45 XDeleteContext does not free the data whose address was saved.
46
47 The XUniqueContext function creates a unique context type that may be
48 used in subsequent calls to XSaveContext.
