The ulimits are stored in /etc/security/limits in two ways: there is a default clause listing all the limits which are in place per default. Every user can have its own stanza with entries overriding these defaults.
Issue "ulimit -a" to see all the limits in place. Issue "ulimit -f <n>" to change the maximum filesize (in disk block units).
I hope this helps.

COPY(9) BSD Kernel Developer's Manual COPY(9)
NAME
copy, copyin, copyout, copystr, copyinstr -- kernel copy functions
SYNOPSIS
#include <sys/types.h>
#include <sys/systm.h>
int
copyin(const void *uaddr, void *kaddr, size_t len);
int
copyout(const void *kaddr, void *uaddr, size_t len);
int
copystr(const void *kfaddr, void *kdaddr, size_t len, size_t *done);
int
copyinstr(const void *uaddr, void *kaddr, size_t len, size_t *done);
DESCRIPTION
The copy functions are designed to copy contiguous data from one address to another. All but copystr() copy data from user-space to kernel-
space or vice-versa.
The copy routines provide the following functionality:
copyin() Copies len bytes of data from the user-space address uaddr to the kernel-space address kaddr.
copyout() Copies len bytes of data from the kernel-space address kaddr to the user-space address uaddr.
copystr() Copies a NUL-terminated string, at most len bytes long, from kernel-space address kfaddr to kernel-space address kdaddr. The
number of bytes actually copied, including the terminating NUL, is returned in *done.
copyinstr() Copies a NUL-terminated string, at most len bytes long, from user-space address uaddr to kernel-space address kaddr. The num-
ber of bytes actually copied, including the terminating NUL, is returned in *done.
RETURN VALUES
The copy functions return 0 on success or EFAULT if a bad address is encountered. In addition, the copystr(), and copyinstr() functions
return ENAMETOOLONG if the string is longer than len bytes.
