.SH DESCRIPTION
|
|
|
|
|
Obsolete function. Use \fIcurl_easy_unescape(3)\fP instead.
|
|
|
|
|
|
|
|
|
|
This function converts the URL encoded string \fBinput\fP 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) are converted to
|
|
|
|
|
their plain text versions.
|
|
|
|
|
|
|
|
|
|
If the \fBlength\fP argument is set to 0, \fIcurl_unescape(3)\fP calls
|
|
|
|
|
strlen() on \fBinput\fP to find out the size.
|
|
|
|
|
|
|
|
|
|
You must \fIcurl_free(3)\fP the returned string when you are done with it.
