Is there a reference for the file* series of commands? I know it's in the C lib (mscvrt.dll), is there a starting place I can look?

Look in MSDN just type the command in the search field and press GO for example:

First Item on the list (also the first on google)

Everything you ever needed to know about RTLs

Doh!! I meant, I would like to reverse-engineer these.. I should have worded my question more accurately ~:\
I would like to make my own fputc(), fgetc(), fopen(), etc.. for purposes of speed and size naturally and to avoid using the mscvrt.dll.

Is there a starting place I can look?

Eek !!! R3v3rs3-3ng1n33r1ng is d@ eV1l !!! Please read the rules. :eek:

Btw, there is no need to rewrite C library file functions : you can use the Win32API instead (CreateFile, ReadFile, WriteFile)...
You can write wrappers functions/macros around those API functions to make them easier to use, if you want...

there's not much use in writing your own FILE * stuff... you'll be IO bound anyway. If you want something speedier, go design your own stuff around win32 file functions.

If you feel you must use FILE * stuff, the interface is documented in just any libc reference, even at . If you need some help implementing it, there's plenty of sources to look at. djgpp libc, cygwin libc, linux libc, etc etc etc.

If you own Visual C/C++, you should have the libc source code. If you don't own a copy... Well, MS used to put old VC libc source code on their ftp site. I'm not sure if they still do so.

Anyway, that would be a better starting point than RE'ing binary files.

Or, you may want to take a look at OpenWatcom libc source code.

Thanks for the link about C run-time reference.:alright:
