NAME

curl_unescape - URL decodes the given string

SYNOPSIS

#include <curl/curl.h>
char *curl_unescape(const char *input, int length);

DESCRIPTION

Obsolete function. Use curl_easy_unescape(3) instead.

This function converts the URL encoded string input to a "plain string" and return that as a new allocated string. All input characters that are URL encoded (%XX where XX is a two-digit hexadecimal number) are converted to their plain text versions.

If the length argument is set to 0, curl_unescape(3) calls strlen() on input to find out the size.

You must curl_free(3) the returned string when you are done with it.

EXAMPLE

int main(void)
{


  CURL *curl = curl_easy_init();


  if(curl) {


    char *decoded = curl_unescape("%63%75%72%6c", 12);


    if(decoded) {


      /* do not assume printf() works on the decoded data */


      printf("Decoded: ");


      /* ... */


      curl_free(decoded);


    }


  }
}

AVAILABILITY

Since 7.15.4, curl_easy_unescape(3) should be used. This function might be removed in a future release.
