property
SYNTAX

ARGUMENTS
argc Specifies the number of arguments.

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.
