strncasecmp
[case insensitive character string compare]

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

DESCRIPTION
strncasecmp compares up to length characters from 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 upper case), strncasecmp returns a number greater than zero. If the two strings are equivalent, strncasecmp returns zero. If *a sorts lexicographically before *b, strncasecmp returns a number less than zero.

COMPLIANCE
strncasecmp is in the Berkeley Software Distribution.

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