STRCASECMP(3)STRCASECMP(3)NAMEstrcasecmp - compare strings, ignoring case
strcasecmp(const char *s1, const char *s2);
strncasecmp(const char *s1, const char *s2, size_t len);
Strcasecmp and strncasecmp 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'.
Strncasecmp compares at most len characters.
