Is there an alternative to sbrk()

[Brent Benson]

I'm trying to port an application to the NeXT computer that uses the
sbrk() UNIX system call.  I got a memory allocation error when
trying to run the program; and the man page says:

	The UNIX system calls `brk' and `sbrk' are not supported
	on the NeXT computer.

Does anyone know of an alternative call that would have the same
functionality (assuming there is one).

Thanks in advance.
