    1.18 +* FUNCTION
    1.19 +* <<strcmp>>---character string compare
    1.20 +* INDEX
    1.21 +* strcmp
    1.22 +* ANSI_SYNOPSIS
    1.23 +* #include <string.h>
    1.24 +* int strcmp(const char *<[a]>, const char *<[b]>);
    1.25 +* TRAD_SYNOPSIS
    1.26 +* #include <string.h>
    1.27 +* int strcmp(<[a]>, <[b]>)
    1.28 +* char *<[a]>;
    1.29 +* char *<[b]>;
    1.30 +* <<strcmp>> compares the string at <[a]> to
    1.31 +* the string at <[b]>.
    1.32 +* RETURNS
    1.33 +* If <<*<[a]>>> sorts lexicographically after <<*<[b]>>>,
    1.34 +* <<strcmp>> returns a number greater than zero.  If the two
    1.35 +* strings match, <<strcmp>> returns zero.  If <<*<[a]>>>
    1.36 +* sorts lexicographically before <<*<[b]>>>, <<strcmp>> returns a
    1.37 +* number less than zero.
    1.38 +* PORTABILITY
    1.39 +* <<strcmp>> is ANSI C.
    1.40 +* <<strcmp>> requires no supporting OS subroutines.
