XSetCommand, XGetCommand - set or read a window's WM_COMMAND property
XSetCommand(display, w, argv, argc)
Display *display;
Window w;
char **argv;
int argc;
Status
XGetCommand(display, w, argv_return, argc_return)
Display *display;
Window w;
char ***argv_return;
int *argc_return;
Specifies the number of arguments.
Returns the number of arguments returned.
Specifies the application's argument list.
Returns the application's argument list.
Specifies the connection to the X server.
Specifies the window.
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.
The command and arguments, null-separated, used to invoke
the application.
The server failed to allocate the requested resource or server
memory.
A value for a Window argument does not name a defined Window.
