curl_strnequal(3) Library Functions Manual curl_strnequal(3)
NAME
curl_strnequal - compare two strings ignoring case
SYNOPSIS
#include <curl/curl.h>
int curl_strnequal(const char *str1, const char *str2, size_t length);
DESCRIPTION
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.
PROTOCOLS
This functionality affects all supported protocols
EXAMPLE
int main(int argc, char **argv)
{
const char *name = "compare";
if(curl_strnequal(name, argv[1], 5))
printf("Name and input matches in the 5 first bytes\n");
}
AVAILABILITY
Added in curl 7.1
RETURN VALUE
Non-zero if the strings are identical. Zero if they are not.
