Return code from system()

["Oliver Elphick" <olly@lfix.co.uk>]

According to the man page for system(), it should return the return code of
the command run, or else -1 or 127.

For me it is returning RC * 256: that is, if the return code is 1, system()
returns 256; if 2, 512 and so on.

Code fragment:

	char *s = "...";
 	int j = system((const char *) s);

dpkg -s libc5:

        Version: 5.4.20-1

Is this a fault in documentation, or in the libc package? Is it unique to me?
