Libraries & CreateNewProc

[itix]

"More specifically, every library call I'm using (DOS, graphics etc.) works, apart from bsdsocket.library calls."

Every process using bsdsocket.library must open that library on its own. Sharing bsdsocketbase is not permitted.

Unfortunately, IIRC Tasks can't cant call dos.library or anything which in turn woild call dos.library

You can call DOS functions from a task if they don't need process structure (file I/O). Those DOS functions which need a process structure are protected against tasks.
