resource. A unique user-defined semaphore should be established for each resource
requiring exclusive access.
The following procedures are available for managing semaphores other than the
checkpoint semaphore. The checkpoint semaphore is managed with the GET^CPSEM
and GIVE^CPSEM procedures.
INIT^SEM

Task Maintenance
The following procedures support various features related to task processing and
shutdown:
GET^TASK^NAME TCBADDR
^SHUTDOWN ^TERMINATE
STOP^TASK WAITED^IO[X]
Pseudo Procedures
TSCODE provides you with a set of pseudo procedure calls that, with some exceptions,
have the same parameters, syntax, meaning, and resultant capabilities as their
counterparts. They comprise a layer of TSCODE between USCODE and the Guardian
file system, NonStop TS/MP server classes, and the TMF component of NonStop
TM/MP that is virtually transparent to USCODE, providing you with a consistent
interface to facilities similar to NonStop systems.
This layer of software allows TSCODE to keep track of each internal I/O operation and
to ensure that every I/O operation is handled correctly at completion time. Pseudo
procedures determine whether an operation is to be handled completely within GDSX or
is to be handled outside GDSX.
Table 8-1 contains a list of the pseudo procedure calls supported by TSCODE. Many
TSCODE-supported utility procedures do not have Guardian file-system counterparts,
and are not included here. A bracketed X at the end of or in the middle of a procedure
name indicates that both local-memory and extended-memory procedures are available.
For example, ^AWAITIO[X] indicates that the ^AWAITIO and ^AWAITIOX procedures
are available.
Caution. The pseudo procedure calls must be used instead of their counterparts.
