ping_send(3)							     liboping							      ping_send(3)

NAME

       ping_send - Send ICMP echo requests to all associated hosts and wait for ICMP echo responses to arrive

SYNOPSIS

	 #include <oping.h>

	 int ping_send (pingobj_t *obj);

DESCRIPTION

       The ping_send method is the actual workhorse of this library. It crafts ICMP packets for the hosts associated with obj and sends them via
       the corresponding sockets. It then waits for echo responses and receives them, writing latency information for each host. The method
       returns after all echo replies have been read or the timeout (set with ping_setopt(3)) is reached.

       After this function returns you will most likely iterate over all hosts using ping_iterator_get(3) and ping_iterator_next (described in the
       same manual page) and call ping_iterator_get_info(3) on each host.

RETURN VALUE

       ping_send returns the number of echo replies received or a value less than zero if an error occurred. Use ping_get_error(3) to receive an
       error message.

NAME

       ping_host_add - Add a host to a liboping object

SYNOPSIS

	 #include <oping.h>

	 int ping_host_add    (pingobj_t *obj, const char *host);
	 int ping_host_remove (pingobj_t *obj, const char *host);

DESCRIPTION

       The ping_host_add method tries to resolve the host argument, open a socket and associate everything with the liboping object obj.

       The obj argument is a pointer to an liboping object, as returned by ping_construct(3).

       The host parameter is a '' terminated string which is interpreted as a hostname or an IP address. Depending on the address family
       setting, set with ping_setopt(3), the hostname is resolved to an IPv4 or IPv6 address.

       The ping_host_remove method looks for host within obj and remove it if found. It will close the socket and deallocate the memory, too.

       The names passed to ping_host_add and ping_host_remove must match. This name can be queried using ping_iterator_get_info(3).

RETURN VALUE

       If ping_host_add succeeds it returns zero. If an error occurs a value less than zero is returned and the last error is saved internally.
       You can receive the error message using ping_get_error(3).

       ping_host_remove returns zero upon success and less than zero if it failed.  Currently the only reason for failure is that the host isn't
       found, but this is subject to change. Use ping_get_error(3) to receive the error message.
