strcasecmp, strncasecmp, stricmp, strincmp - compare strings, ignoring
short stricmp (const char *s1, const char *s2);
short strincmp (const char *s1, const char *s2, unsigned n);
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 as 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 \0.
The strncasecmp compares at most len characters.
stricmp and strincmp are functionally identically equal to, and imple-
mented in terms of, strcasecmp and strncasecmp, respectively.

The strcasecmp and strncasecmp functions first appeared in 4.4BSD.
