DESCRIPTION
The function sets the command and arguments used to invoke the applica‐
tion. (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.
can generate and errors.
The 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, fills in the argv_return and argc_return argu‐
ments and returns a nonzero status. Otherwise, it returns a zero sta‐
tus. If the data returned by the server is in the Latin Portable Char‐
acter 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
PROPERTIES
