NAME
strcasecmp, strncasecmp - compare two strings ignoring case SYNOPSIS
#include
int strcasecmp(const char *s1, const char *s2); int strncasecmp(const char *s1, const char *s2, sizet n); DESCRIPTION The strcasecmp() function compares the two strings s1 and s2, ignoring the case of the characters. It returns an integer less than, equal to, or greater than zero if s1 is found, respectively, to be less than, to match, or be greater than s2. The strncasecmp() function is similar, except it compares the only first n bytes of s1. RETURN VALUE The strcasecmp() and strncasecmp() functions return an integer less than, equal to, or greater than zero if s1 (or the first n bytes thereof) is found, respectively, to be less than, to match, or be greater than s2.
