NAME
XSetCommand, XGetCommand - set or read a window's WM_COMMAND property
SYNTAX
int XSetCommand(Display *display, Window w, char
**argv, int argc);
Status XGetCommand(Display *display, Window w, char
***argv_return, int *argc_return);
ARGUMENTS
argc
Specifies the number of arguments.
argc_return
Returns the number of arguments returned.
argv
Specifies the application's argument list.
argv_return
Returns the application's argument list.
display
Specifies the connection to the X server.
w
Specifies the window.
DESCRIPTION
The
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.
XSetCommand
can generate
BadAlloc
and
BadWindow
errors.
The
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,
XGetCommand
fills in the argv_return and argc_return arguments
and returns a nonzero status.
Otherwise, 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
XFreeStringList.
PROPERTIES
WM_COMMAND
The command and arguments, null-separated, used to invoke the
application.
DIAGNOSTICS
BadAlloc
The server failed to allocate the requested resource or server memory.
BadWindow
A value for a Window argument does not name a defined Window.
