It was just a thought, and it did not work. :) Other flavors of Unix
are not too important in this case: I'm writing a FreeBSD assembly
language tutorial. Though I do discuss portability issues in it.
I'm writing the tutorial, not because I'm the expert (I am, on assembly
language, but not on Unix system calls--yet), but because, in my
experience, it is the best way to learn.

Unfortunately, that only works in C. :)
I tried to figure out how to allocate memory, but, so far, was completely
unsuccessful. I studied the source for the C malloc, but did not understand
any of it. It uses something called mmap. I read the man page for mmap,
and was totally frustrated. It talks about mapping files into memory,
but I am not looking for files. It talks about passing an address to the
function. I don't get it... What address? I want it to allocate memory
for me and tell me its address. How am I supposed to know what address
is available???
Thanks,
Adam
