curl_escape - URL encodes the given string
SYNOPSIS
#include <curl/curl.h>
char *curl_escape( char *url, int length );
DESCRIPTION
This function will convert the given input string to an
URL encoded string and return that as a new allocated
string. All input characters that are not a-z, A-Z or 0-9
will be converted to their "URL escaped" version. If a
sequence of %NN (where NN is a two-digit hexadecimal num
ber) is found in the string to encode, that 3-letter com
bination will be copied to the output unmodifed, assuming
that it is an already encoded piece of data.
If the 'length' argument is set to 0, curl_escape() will
use strlen() on the input 'url' string to find out the
size.
You must free() the returned string when you're done with
it.
RETURN VALUE
A pointer to a zero terminated string or NULL if it
failed.
