The Cookie Jar
The
CookieJar is a structure in memory containing entries called 'cookies' which are placed in the 'jar' by the operating system or
TSR applications. Applications can test for the presence of a cookie to determine the presence of a hardware device or system feature.
The location of the cookie jar is determined by the address contained in the system variable
_p_cookies (
0x05A0). If no cookie jar has been allocated yet, this entry will contain
NULL (
0).
