XSetCommand(3) XLIB FUNCTIONS XSetCommand(3)
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 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 ex-
ists, it is of type STRING and format 8. If sufficient memory can be
allocated to contain the string list, XGetCommand fills in the argv_re-
turn 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 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.
