What i have read in one of my book is :

A constant integer written in headecimal form will take the first of the following type whose size is sufficient to represent it correctly : int, unsigned int, long int, unsigned long int.
you can still force the compiler to use a type long or unsigned by adding the L|l or U|u :

0xFFl
0xFFFFu
0xFFFFlu

In the case your constant is positive and exceed the capacity of the type unsigned long int
OR
In the case your constat is negative and is lower than the lowest number that can be represented in with the type int
... then the ANSI norm does not specify the behaviour (so it may depend on the implementation of your compiler, some will truncate bits to only keep those with 'heavy weight' ... some may return strange result...)

curl_unescape

curl_unescape(3)						  libcurl Manual						  curl_unescape(3)

NAME

       curl_unescape - URL decodes the given string

SYNOPSIS

       #include <curl/curl.h>

       char *curl_unescape( char *url, int length );

DESCRIPTION

       Obsolete function. Use curl_easy_unescape(3) instead!

       This  function  will  convert  the  given URL encoded input string 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) will be converted to their plain text versions.

       If the 'length' argument is set to 0, curl_unescape() will use strlen() on the input 'url' string to find out the size.

       You must curl_free() the returned string when you're done with it.

AVAILABILITY

       Since 7.15.4, curl_easy_unescape(3) should be used. This function will be removed in a future release.

RETURN VALUE

       A pointer to a zero terminated string or NULL if it failed.

SEE ALSO

       curl_easy_escape(3), curl_easy_unescape(3), curl_free(3), RFC 2396

libcurl 7.7							   22 March 2001						  curl_unescape(3)
