DESCRIPTION

30       The XSetCommand function sets the command and arguments used to invoke
31       the application.  (Typically, argv is the argv array of your main pro‐
32       gram.)  If the strings are not in the Host Portable Character Encoding,
33       the result is implementation-dependent.
34
35       XSetCommand can generate BadAlloc and BadWindow errors.
36
37       The XGetCommand function reads the WM_COMMAND property from the speci‐
38       fied window and returns a string list.  If the WM_COMMAND property
39       exists, it is of type STRING and format 8.  If sufficient memory can be
40       allocated to contain the string list, XGetCommand fills in the
41       argv_return and argc_return arguments and returns a nonzero status.
42       Otherwise, or if any other error is encountered, it returns a zero sta‐
43       tus.  If the data returned by the server is in the Latin Portable Char‐
44       acter Encoding, then the returned strings are in the Host Portable
45       Character Encoding.  Otherwise, the result is implementation-dependent.
46       To free the memory allocated to the string list, use XFreeStringList.
