JDE API - Getting Complete List of JDE API's


Can I get the complete list of JDE API's? I searched the internet and found the .chm file for the API list but it does not have the complete API's. I extracted the dll file of JDE and found about 2000+ API's. So is there any way I can get the API list and their input and output parameters?
Also just by looking at the API eg:jdeCacheInit (HUSER hUser, HCACHE *hCache, char * szCacheName, JDECMINDEXSTRUCT *lpIndex);
How can I determine which are the input and output parameters without searching it in .chm file?
Please point me in the right direction.
