.Sh SYNOPSIS
|
|
.In ulimit.h
|
|
.Ft long
|
|
.Fn ulimit "int cmd" "..."
|
|
.Sh DESCRIPTION
|
|
The
|
|
.Fn ulimit
|
|
function will get and set process limits.
|
|
Currently this is limited to the maximum file size.
|
|
The
|
|
.Fa cmd
|
|
argument is one of the following:
|
|
.Bl -tag -width ".Dv UL_GETFSIZE"
|
|
.It Dv UL_GETFSIZE
|
|
will return the maximum file size in units of 512 blocks of
|
|
the current process.
|
|
.It Dv UL_SETFSIZE
|
|
will attempt to set the maximum file size of the current
|
|
process and its children with the second argument expressed as a long.
|
|
.El
|
|
.Sh RETURN VALUES
|
|
Upon successful completion,
|
|
.Fn ulimit
|
|
returns the value requested;
|
|
otherwise the value \-1 is returned and the global variable
|
|
.Va errno
|
|
is set to indicate the error.
|
|
.Sh ERRORS
|
|
The
|
|
.Fn ulimit
|
|
function will fail if:
|
|
.Bl -tag -width Er
|
|
.It Bq Er EINVAL
|
|
The command specified was invalid.
|
|
.It Bq Er EPERM
|
|
The limit specified to
|
|
.Fn ulimit
|
|
would have raised the maximum limit value,
|
|
and the caller is not the super-user.

|
|
The
|
|
.Fn ulimit

function first appeared in

|
|
.Sh BUGS
|
|
The
|
|
.Fn ulimit
|
|
function provides limited precision for
|
|
setting and retrieving process limits.
|
|
If there is a need for greater precision than the
|
|
type
|
|
.Vt long
|
|
provides, the
|
|
.Xr getrlimit 2
|
|
and
|
|
.Xr setrlimit 2
|
|
functions should be considered.
