curl_strequal, curl_strnequal - case insensitive string comparisons
#include <curl/curl.h>
int
curl_strequal(const char *str1, const char *str2);
int curl_strnequal(const char *str1, const char *str2,
size_t length);
The curl_strequal() 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.
The curl_strnequal() function is similar, except it only compares the first length characters of str1.
These functions are provided by libcurl to enable applications to compare strings in a truly portable manner. There are no standard portable case insensitive string comparison functions. These two work on all platforms.
int main(int
argc, char **argv)
{
const char *name = "compare";
if(curl_strequal(name, argv[1]))
printf("Name and input matches\n");
if(curl_strnequal(name, argv[1], 5))
printf("Name and input matches in the 5 first
bytes\n");
}
Always
Non-zero if the strings are identical. Zero if they are not.
