.TH curl_unescape 3 "22 March 2001" "libcurl 7.7" "libcurl Manual"
.SH NAME
curl_unescape - URL decodes the given string
.SH SYNOPSIS
.B #include <curl/curl.h>
.sp
.BI "char *curl_unescape( char *" url ", int "length " );"
.ad
.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 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.
