curl_strequal, curl_strnequal - case insensitive string comparisons

#include <curl/curl.h>

int curl_strequal(char **/str1/, char */str2/);*

int curl_strnequal(char **/str1/, char */str2/, size_t len);*

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 len 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.

  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");

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().

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