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