I have look at adding API function to lite-C and I have come up with this list of API function from the msvcrt DLL.
Of course you can use this code free of charge. I do not know if this is the best way to do it, but it works for me. I have noticed that so many people asked for functions like 'sprintf' and FILE commands like 'fopen' to 'fclose'.
This is all (compatable) functions from the DLL which should be in the Windows System32 folder.
People, please reply if you use it. I will like to know if you find this useful. I would like to know how to improve it!
... So do I get Lite-C free now...? lol!
