XSetCommand(3X11)XSetCommand(3X11)NAME
XSetCommand, XGetCommand - set or read a window's WM_COMMAND property
SYNOPSIS
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;
ARGUMENTS
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.
DESCRIPTION
The XSetCommand function sets the command and arguments used to invoke
the application. (Typically, argv is the argv array of your main pro‐
gram.) 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 speci‐
fied 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
The command and arguments, null-separated, used to invoke the applica‐
tion.
DIAGNOSTICS
The server failed to allocate the requested resource or server memory.
A value for a Window argument does not name a defined Window.
