curl_strequal(3) libcurl Manual curl_strequal(3)
NAME
curl_strequal, curl_strnequal - case insensitive string comparisons
SYNOPSIS
#include <curl/curl.h>
int curl_strequal(char *str1, char *str2);
int curl_strnequal(char *str1, char *str2, size_t length);
DESCRIPTION
The curl_strequal() function compares the two strings str1 and str2,
ignoring the case of the characters. It returns a non-zero (TRUE) inte-
ger if the strings are identical.
The curl_strnequal() function is similar, except it only compares the
first lenght characters of str1.
These functions are provided by libcurl to enable applications to com-
pare strings in a truly portable manner. There are no standard portable
case insensitive string comparison functions. These two work on all
platforms.
EXAMPLE
if(curl_strequal(name, input))
printf("Name and input matches\n");
if(curl_strnequal(name, input, 5))
printf("Name and input matches in the 5 first bytes\n");
AVAILABILITY
These functions will be removed from the public libcurl API in a near
future. They will instead be made "available" by source code access
only, and then as curlx_strequal() and curlx_strenqual().
RETURN VALUE
Non-zero if the strings are identical. Zero if they are not.
