I am allocating pointers right and left and after a certain point the program will not allow me to allocate any more. I have tried to compile using the -LARGE option to get a large model memory, only I get this response I am using a make file that looks like the following: # # OBJ = sumphero.o miracle.o rdfiles.o srt.o mathfunc.o CFLAGS = -LARGE sumph: $(OBJ) cc $(CFLAGS) $(OBJ) -o sumphero $(OBJ): sumphero.h structs.h macdef.h The environment I am using is SCO UNIX System V/386 release 3.2.0 on an IBM PS/2 Model 70 386. (Customer supplied not company choice.) If anyone has an idea on how to be able to allocate more space, I would love to hear it. Also, some of the pointers I am allocating are to large structures, to to the real stuff. After about 400K bytes allocated the program quits allocating space. Is there some way around this. Thanks, Cheryl Lindsey ..!uunet!emory!bluemtn!cheryl

I note with bemusement that you've went into great detail about the machine you are using, but didn't bother to mention the somewhat important details of how much memory your system has and how the per-process limits are configured by default. That would certainly help to diagnose the problem. A few other questions I have -- (1) Are you ever *freeing* any of the pointers that you are allocating? (2) When you say that you are allocating "pointers", do you mean that you are allocating space for things like structures and then assigning the address of that allocated space to a pointer? (3) What are you using for allocation, malloc? (4) What error do you get when you can no longer allocate -- out of memory, or something else?
