15 This function converts the given URL encoded input string to a "plain
16 string" and returns that in an allocated memory area. All input charac‐
17 ters that are URL encoded (%XX where XX is a two-digit hexadecimal num‐
18 ber) are converted to their binary versions.
19
20 If the length argument is set to 0 (zero), curl_easy_unescape() will
21 use strlen() on the input url string to find out the size.
22
23 If outlength is non-NULL, the function will write the length of the
24 returned string in the integer it points to. This allows an escaped
25 string containing %00 to still get used properly after unescaping.
26
27 You must curl_free(3) the returned string when you're done with it.
28
30 Added in 7.15.4 and replaces the old curl_unescape() function.
31
33 A pointer to a zero terminated string or NULL if it failed.
