Thread Local Storage (TLS) allows each task to have task specific variables that are typically required by compilers and their run-time library.  TLS is optional and only currently available for a couple of compilers (CCES from Analog Devices and Embedded Workbench from IAR).  TLS requires that you enable this feature by setting the TLS table size (see the MicroC/OS-II user’s manual) through the #define OS_TLS_TBL_SIZE and, if defined, must be greater than 0. 

TLS is mandatory if you use non-reentrant library functions that are not protected by either a mutex or a semaphore. Forexamplethe‘strtok()’ function needs to keep a copy of a pointer forfurtherinvocationsofstrtok().  This local pointer is now saved as part of the TLS management when TLS is enabled and thus does not require that you protect the non-reentrant code with a mutex or a semaphore. 

1)  A number of ‘internal’ functions have been added to support TLS.  However, as the user, you only need to:

Added OSTaskRegGetID() to dynamically assign task IDs instead of assigning task IDs statically through #define constants.  It’s important that you either use ‘dynamic task register ID allocation’ or ‘static register ID allocation’ but not both.  The preferred method is to use OSTaskRegGetID() throughout your code.

You now need to allocate an INT8U variable for each task register IDs and use those variables to specify the desired task register.  In other words:

INT8U  MyTaskRegID;

:

:

    MyTaskRegID = OSTaskRegGetID(&err);

...

            The new value of these #defines are either 0 (to disable naming the object) or 1 (to enable naming the object).

...

            Added support for multi-pend.
