Function NbDOpen() Foundation

Opens NetBIOS send and receive buffers for datagram services.

Syntax
NbDOpen( <cLocalName>          , ;
         [<nReceiveBufferSize>], ;  // Default: NIL
         [<nSendBufferSize>]   , ;  // Default: NIL
         [<cRemoteName>]       , ;  // Default: NIL
         [<nPackageSize>]        ;  // Default: 512
       ) --> nCommunicationHandle
Return

Returns a numeric value >0 which is to be used as communication handle for other Nb..() and Ppc..() functions or 0 in case of an error.

Description

<cLocalName>

A string of max. 15 characters. It serves as the local workstation's NetBIOS name for communication with other workstations in the network. If <cLocalName> does not exist in the local name table it is added automatically (see NbAddName()).

<nReceiveBufferSize>

If this parameter is omitted no receive buffer will be installed on the local workstation. In this case it is only possible to send datagrams. Otherwise it is a numeric value which must fall between <nPackageSize> and 64 kb.

<nSendBufferSize>

If this parameter is omitted no send buffer will be installed on the local workstation. In this case it is only possible to receive datagrams. Otherwise it is a numeric value which must fall between <nPackageSize> and 64 kb.

<cRemoteName>

If this parameter is omitted the local workstation will only be able to send/receive broadcast datagrams. Otherwise a communication is possible to all remote workstations which have entered <cRemoteName> to their local name table.

<nPackageSize>

This parameter defines the size of data packages to send/receive. It defaults to 512 bytes which is the maximum size.
