curl_strequal - Man Page

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(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.

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");



Return Value

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