NUTSCAN_IP_RANGES_IT(3)

NAME
nutscan_ip_ranges_iter_init - Begin iteration of an IP address range using a `nutscan_ip_range_list_iter_t` structure.

SYNOPSIS

        #include <nut-scan.h>

        char * nutscan_ip_ranges_iter_init(
                nutscan_ip_range_list_iter_t *irliter,
                const nutscan_ip_range_list_t *irl);

DESCRIPTION

The nutscan_ip_ranges_iter_init() function can prepare an iterator from the specified nutscan_ip_range_list_t structure, saving it into the caller-provided nutscan_ip_range_list_iter_t helper object.

Different iterators may be created to walk the same nutscan_ip_range_list_t list from different scans independently, but the list and its contents should not be freed while anyone references it.

This function skips work if:

    • the structure pointer is NULL (NULL is returned);

    • the structure pointer’s ip_range list is NULL (NULL is returned).

Returns the first IP address from the first registered IP address range. Subsequent addresses can be returned by nutscan_ip_ranges_iter_inc(). The caller SHOULD NOT free this string while iterating.

NOTES

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