curl_unescape(3)

NAME
curl_unescape - URL decodes the given string

SYNOPSIS
#include <curl/curl.h>

char *curl_unescape( char *url, int length );

DESCRIPTION
This function will convert the given URL encoded input string 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, or +) will be converted to their plain text versions (up to a ? letter, no + letters to the right of a ? letter will be converted). If the 'length' argument is set to 0, curl_unescape() will use strlen() on the input 'url' string to find out the size. You must curl_free() the returned string when you're done with it.

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