NAME

strcasecmp - compare strings, ignoring case

SYNOPSIS

Fd #include <string.h> Ft int Fn strcasecmp const char *s1 const char *s2 Ft int Fn strncasecmp const char *s1 const char *s2 size_t len

DESCRIPTION

The Fn strcasecmp and Fn strncasecmp functions compare the null-terminated strings Fa s1 and Fa s2 and return an integer greater than, equal to, or less than 0, according as Fa s1 is lexicographically greater than, equal to, or less than Fa 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 Fn strncasecmp compares at most Fa len characters.

HISTORY
