strcasecmp, strncasecmp - compare strings, ignoring case
#include <string.h>
int
strcasecmp(const char *s1, const char *s2);
int
strncasecmp(const char *s1, const char *s2, size_t len);
The strcasecmp() and strncasecmp() functions compare the
null-terminated
strings s1 and s2 and return an integer greater than, equal
to, or less
than 0, according to whether s1 is lexicographically greater
than, equal
to, or less than s2 after translation of each corresponding
character to
lower-case. The strings themselves are not modified. The
comparison is
done using unsigned characters, so that `200' is greater
than ` '.
strncasecmp() compares at most len characters.

The strcasecmp() and strncasecmp() functions first appeared
in 4.4BSD.
