^SERVERCLASS_SEND_INFO_
records contain the calling task number, PATHMON process name, server class
name, buffer, and server class send operation number used with this procedure.
See Tracing GDSX on page 2-80 for more information.
^SERVERCLASS_SEND_INFO_
This procedure allows USCODE to retrieve information about the last initiated or
completed call to ^SERVERCLASS_SEND_INFO_ directly from TS/MP server classes.
See Appendix D, Using Pseudo Procedures in a TS/MP Environment for an example of
using this procedure.
When the return status of ^SERVERCLASS_SEND_ is 233, indicating an error with the
call, you should can call ^SERVERCLASS_SEND_INFO_ to receive additional
Pathsend and file-system error information.
If the return status of ^SERVERCLASS_SEND_ is 0, the call was successful. If you
call ^SERVERCLASS_SEND_INFO_ in this case, Pathsend and the file system also
return a value of 0.
The syntax, condition code settings, and considerations regarding this procedure are
the same as the counterpart in the NonStop TS/MP Pathsend and Server
Programming Manual.
^SETMODE
This procedure is used to set device-dependent functions.
A call to the SETMODE procedure is rejected with an error indication if nowait
operations are pending on the specified file.
Except for the following considerations, the syntax, condition code settings, and
considerations regarding this procedure are the same as the counterpart in the
Guardian Procedure Calls Reference Manual.
Considerations
Because the working stack images of tasks are swapped to and from an extended data
segment during I/O operations, I/O must be performed to and from global buffers.
^SETMODENOWAIT
This procedure sets device-dependent functions in a nowait manner on nowait files.
Except for the following considerations, the syntax, condition code settings, and
considerations regarding this procedure are the same as the counterpart in the
Guardian Procedure Calls Reference Manual.
