The curldown conversion accidentally replaced daniel@haxx.se with just daniel.se. This reverts back to the proper email address in the curldown docs as well as in a few other stray places where it was incorrect (while unrelated to curldown).

# NAME
|
|
|
|
curl_unescape - URL decodes the given string
|
|
|
|
# SYNOPSIS
|
|
|
|
~~~c
|
|
#include <curl/curl.h>
|
|
|
|
char *curl_unescape(const char *input, int length);
|
|
~~~
|
|
|
|
# DESCRIPTION
|
|
|
|
Obsolete function. Use curl_easy_unescape(3) instead.
|
|
|
|
This function converts the URL encoded string **input** 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 **length** argument is set to 0, curl_unescape(3) calls
|
|
strlen() on **input** to find out the size.
|
|
|
|
You must curl_free(3) the returned string when you are done with it.
|
|

# EXAMPLE
|
|
|
|
~~~c
|
|
int main(void)
|
|
{
|
|
CURL *curl = curl_easy_init();
|
|
if(curl) {
|
|
char *decoded = curl_unescape("%63%75%72%6c", 12);
|
|
if(decoded) {
|
|
/* do not assume printf() works on the decoded data */
|
|
printf("Decoded: ");
|
|
/* ... */
|
|
curl_free(decoded);
|
|
}
|
|
}
|
|
}
|
|

|
|
|
|
# AVAILABILITY
|

|
|
be removed in a future release.
