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 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, 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.
