.TH curl_unescape 3 "November 04, 2020" "libcurl 7.77.0" "libcurl Manual"

.SH NAME
curl_unescape - URL decodes the given string
.SH SYNOPSIS
.B #include <curl/curl.h>
.sp
.BI "char *curl_unescape( const char *" url ", int "length " );"
.ad
.SH DESCRIPTION
Obsolete function. Use \fIcurl_easy_unescape(3)\fP instead!

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) will be
converted to their plain text versions.

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 \fIcurl_free(3)\fP the returned string when you're done with it.
.SH AVAILABILITY
Since 7.15.4, \fIcurl_easy_unescape(3)\fP should be used. This function will
be removed in a future release.
.SH RETURN VALUE
A pointer to a null-terminated string or NULL if it failed.
.SH "SEE ALSO"
