xlat_opst

This function translates the operating status bits in g_op_stat to English.

Calling sequence:

explan = xlat_opst( );

Arguments:

None, since the operating status is a global variable.

Returned values:

character

pointer whose object is a string suitable for printing. The

string length does not exceed 80 characters (79 plus the terminating zero
byte).

Note that xlat_opst has an internal string buffer and returns a pointer to
that buffer. Calling xlat_opst destroys the previous contents of the buffer.
This means that you must use the string returned by this routine before you
call the routine again.

Here’s a typical use of this routine:

printf(“status: %s\n”, xlat_opst( ));
