	Name	Description
in	sa	Specifies a pointer to the socket address structure that holds address information about the host to search for.
in	node	Specifies a pointer to the buffer used to get the host name.
in	nodeLen	Specifies the size in bytes of the buffer used to get the host name.
in	service	Specifies a pointer to the buffer used to get the service name.
in	serviceLen	Specifies the size in bytes of the buffer used to get the service name.
in	flags	Specifies the flags used to set search options. Specify `0` or a bitwise OR of the following values.`NI_NOFQDN`: Gets only the node name part of the fully qualified domain name (FQDN) as the host name. `NI_NUMERICHOST`: Gets the host name by converting the host address included in the socket address structure to a string in dot-decimal notation. `NI_NAMEREQD`: If the search-target host is not found, does not substitute a string converted from the numeric format host address; instead, treats the situation as an error (`SO_EAI_NONAME`). `NI_NUMERICSERV`: Gets the service name by converting the service (port number) included in the socket address structure to a string in numeric notation.

Returns 0 if successful.

Searches for the host name and service name based on the host's address information.

Since this function might query the DNS server, it blocks until the search is complete.
