curl_strnequal3
Compare two strings ignoring case
Usage
#include <curl/curl.h> int curl_strnequal(const char *str1, const char *str2, size_t length);
Overview
The curl_strnequal(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 compares no more than the first length bytes of str1 and str2.
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.

Examples
int main(int argc, char *argv[])
{
static const char *name = "compare";
if(curl_strnequal(name, argv[1], 5))

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