NAME

curl_strequal - compare two strings ignoring case

SYNOPSIS

#include <curl/curl.h>

int curl_strequal(const char *str1, const char *str2);

DESCRIPTION

The curl_strequal(3) function compares the two strings str1 and str2, ignoring the case of the characters. It returns a non-zero (TRUE) integer if the strings are identical.

This function uses plain ASCII based comparisons completely disregarding the locale - contrary to how strcasecmp and other system case insensitive string comparisons usually work.

This function is provided by libcurl to enable applications to compare strings in a truly portable manner. There are no standard portable case insensitive string comparison functions. This function works on all platforms.

}

RETURN VALUE

Non-zero if the strings are identical. Zero if they are not.
