strncasecmp---case insensitive character string compareSynopsis
#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.
Portability
strncasecmp is in the Berkeley Software Distribution.
strncasecmp requires no supporting OS subroutines. It uses
tolower() from elsewhere in this library.
