|
|
|
Arguments:
|
|
|
|
DomainInfo - Hosted domain sending the datagram
|
|
|
|
IpAddress - IpAddress of the machine to send the message to.
|
|
If zero, UnicodeDestinationName must be specified.

|
If ALL_IP_TRANSPORTS, UnicodeDestination must be specified but the datagram
|
|
will only be sent on IP transports.
|
|
|
|
UnicodeDestinationName -- Name of the server to send to.
|
|
|
|
NameType -- Type of name represented by UnicodeDestinationName.
|
|
|
|
TransportName -- Name of the transport to send on.
|
|
Use NULL to send on all transports.
|
|
|
|
OemMailslotName -- Name of the mailslot to send to.
|
|
|
|
Buffer -- Specifies a pointer to the mailslot message to send.
|
|
|
|
BufferSize -- Size in bytes of the mailslot message
|
|
|
|
Return Value:
|
|
|
|
Status of the operation.
|
|
|
|
STATUS_NETWORK_UNREACHABLE: Cannot write to network.
