STRCASECMP(3)

NAME
strcasecmp - compare strings, ignoring case

SYNOPSIS
#include <string.h>
int
strcasecmp(const char *s1, const char *s2);
int
strncasecmp(const char *s1, const char *s2, size_t len);

DESCRIPTION
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.
