/* 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.
