curl_unescape(3)

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
CURL *curl = curl_easy_init();
if(curl) {
  int decodelen;
  char *decoded = curl_unescape("%63%75%72%6c", 12, &decodelen);
  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.

RETURN VALUE
A pointer to a null-terminated string or NULL if it failed.
