NAME
curl_unescape - URL decodes the given string
SYNOPSIS
#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
CURL *curl = curl_easy_init();
if(curl) {
int decodelen;
char *decoded = curl_unescape("%63%75%72%6c", 12, &decodelen);
if(decoded) {
/* do not assume printf() works on the decoded data! */
printf("Decoded: ");
/* ... */
curl_free(decoded);
}
}
AVAILABILITY
Since 7.15.4, curl_easy_unescape(3) should be used. This function might
be removed in a future release.
RETURN VALUE
A pointer to a null-terminated string or NULL if it failed.
