NUTSCAN_INIT_IP_RANGES(3)
=========================

NAME
----

nutscan_init_ip_ranges - Initialize contents of a `nutscan_ip_range_list_t`
structure (and optionally create one in the first place).

SYNOPSIS
--------

------
	#include <nut-scan.h>

	nutscan_ip_range_list_t * nutscan_init_ip_ranges(nutscan_ip_range_list_t *irl);
------

DESCRIPTION
-----------

The *nutscan_init_ip_ranges()* function can prepare a `nutscan_ip_range_list_t`
structure by zeroing out its fields.  If the argument is `NULL`, the structure
is dynamically allocated.  Either way, a pointer to it is returned.

A structure passed by caller is not assumed to have any valid contents to free,
as it may have garbage from stack after allocation.

The caller must free the contents of the structure after completing its use
by calling `nutscan_free_ip_ranges` (after which the structure can be re-used),
and explicitly `free()` the structure object itself if it was allocated
dynamically (e.g. by originally calling `nutscan_init_ip_ranges(NULL)`).

NOTES
-----

Technically, the function is currently defined in 'nutscan-ip.h' file.
