- /* File : strcmp.c
- Author : Richard A. O'Keefe.
- Updated: 10 April 1984
- Defines: strcmp()
-
- strcmp(s, t) returns > 0, = 0, or < 0 when s > t, s = t, or s < t
- according to the ordinary lexicographical order. To test for
- equality, the macro streql(s,t) is clearer than !strcmp(s,t). Note
- that if the string contains characters outside the range 0..127 the
- result is machine-dependent; PDP-11s and VAXen use signed bytes,
- some other machines use unsigned bytes.
