.SH DESCRIPTION
|
|
The
|
|
.ZN XSetCommand
|
|
function sets the command and arguments used to invoke the
|
|
application.
|
|
(Typically, argv is the argv array of your main program.)
|
|
If the strings are not in the Host Portable Character Encoding,
|
|
the result is implementation-dependent.
|
|
.LP
|
|
.ZN XSetCommand
|
|
can generate
|
|
.ZN BadAlloc
|
|
and
|
|
.ZN BadWindow
|
|
errors.
|
|
.LP
|
|
The
|
|
.ZN XGetCommand
|
|
function reads the WM_COMMAND property from the specified window
|
|
and returns a string list.
|
|
If the WM_COMMAND property exists,
|
|
it is of type STRING and format 8.
|
|
If sufficient memory can be allocated to contain the string list,
|
|
.ZN XGetCommand
|
|
fills in the argv_return and argc_return arguments
|
|
and returns a nonzero status.
|
|
Otherwise, or if any other error is encountered, it returns a zero status.
|
|
If the data returned by the server is in the Latin Portable Character Encoding,
|
|
then the returned strings are in the Host Portable Character Encoding.
|
|
Otherwise, the result is implementation-dependent.
|
|
To free the memory allocated to the string list, use
|
|
.ZN XFreeStringList .
|
|
