curl_strequal - case insensitive string comparisons

Name

curl_strequal - compare two strings ignoring case

Synopsis

#include <curl/curl.h>
 
int curl_strequal(const char *str1, const char *str2);

Description

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.

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_strequal(name, argv[1]))
    printf("Name and input matches\n");
}

Availability

Added in curl 7.1

Return value

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