PAR AMETERS
Input
dialog_id
An identifier, previously returned from DCE_SERVERCLASS_DIALOG_BEGIN_() call
that has initiated the dialog with the server process in the Pathway server class.
message_buffer
Contains the message to send to the server class.
request_len
Contains the byte length of the data contained in message_buffer.
maximum_reply_len

LINKMON process waits for the completion of this operation. This value must be either
- 1 or greater than 0 (zero).The default value of this parameter is -1D (wait indefinitely).
If the send is still in progress when this timeout expires, then the send is canceled. An

show Pathsend error 918 (FEScSendOperationAborted) and Guardian file-system error

parameter is provided for compatibility with the Guardian

operations. This parameter is provided for compatibility with the Guardian
SERVERCLASS_DIALOG_SEND_ procedure.
