strcasecmp
[case insensitive character string compare]

SYNOPSIS
#include<string.h>
int strcasecmp(const char *a, const char *b);

DESCRIPTION
strcasecmp compares the string at a to the string at b in a case-insensitive manner.

RETURNS
If *a sorts lexicographically after *b (after both are converted to uppercase), strcasecmp returns a number greater than zero. If the two strings match, strcasecmp returns 0. If *a sorts lexicographically before *b, strcasecmp returns a number less than zero.

COMPLIANCE
strcasecmp is in the Berkeley Software Distribution.

strcasecmp requires no supporting OS subroutines. It uses tolower() from elsewhere in this library.
