When the amout of memory is too big , malloc returns a null pointer.
I'd like to know if there is other ways to allocate memory. Maybe with dpmi
functions ? I couldnt find doc on it.
I know there r functions called like _dpmi_memory_allocate . I also saw
allocate ldt ... But i dunno how to use them. I used to program c with
borland Turboc , there was only malloc and xms. I couldnt load big
objects...
I hope someone can help me ?
