[static]

The ulimit builtin, used for setting resource limits.

Defined in builtin_ulimit.c.

static rlim_t get	(	int	resource,
		int	hard
	)			[static]

Return the value for the specified resource limit.

This function does _not_ multiply the limit value by the multiplier constant used by the commandline ulimit.

static int set	(	int	resource,
		int	hard,
		int	soft,
		rlim_t	value
	)			[static]

Set the new value of the specified resource limit.

This function does _not_ multiply the limit value by the multiplier constant used by the commandline ulimit.
