Using Procedures With pTAL Address Types

These procedures use pTAL data types that support the address types WADDR,

BADDR, EXTADDR, and PROCPTR:

When converting TAL programs, use the pTAL compiler SYNTAX directive to enable

syntax checking. That detects whether the program requires changes.

C and C++ programs do not require changes.

For more details, see the procedure’s description in the

Guardian Procedure Calls

Reference Manual

Writing Multithreaded Programs

Native processes do not maintain the TNS register and stack architecture. Therefore,

user-written multithreaded programs that directly manipulate TNS registers and the

stack require changes to be converted to native mode. Programs must use a new set

of multithreaded support procedures. The multithreaded support procedures enable

programs to save and restore thread context and to create the context for new threads.

Both TNS and native programs can use the multithread support procedures. See

Support Note S96001, “T9050: User-Level TNS/R Native Thread Primitives” for details.

Calling Code You Add to the System Library

If a TNS program calls code that you have added to the system library, the code added

to the system library must be converted to TNS/E native code when you convert the

program.

If both TNS processes (running in interpreted mode or accelerated mode) and native

processes call code you add to the system library, you need two versions of the code:

one that has been accelerated and one that has been compiled with a TNS/E native

compiler. The accelerated and TNS/E native versions can contain the same procedure
