curl_unescape(3) Library Functions Manual curl_unescape(3)
NAME
curl_unescape - URL decode a 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.

/* do not assume printf() works on the decoded data */
printf("Decoded: ");
/* ... */
curl_free(decoded);
}
}
}
