void Enter_Shared_Varblk_Section(RT_INTEGER index, RT_INTEGER caller_id);
procedure Enter_Shared_Varblk_Section(index : RT_INTEGER;
Note A default implementation is not provided for these callouts.

AutoCode Reference
The first formal argument represents which processor the access is taking
place on. Processor numbers are 1-based. The second formal argument
represents the global reference number for which the variable block is
being accessed.
The following code uses the
shared variable block generated code with callouts, using the
Enter_Shared_Varblk_Section(1, 4);
proc2_4_1 = block5[0];
proc2_4_2 = block5[1];
Leave_Shared_Varblk_Section(1, 4);
Entering with Extended Procedure Info Option Specified
The prototype of the callout for entering a shared variable block critical
section with the extended procedure info option is:
The formal argument,
which the variable block is being accessed. The second formal argument,
, represents a unique identifier for the caller.
caller_id
Leaving with Extended Procedure Info Option Specified
The prototype of the callout for leaving a shared variable block critical
section with the extended procedure info option is:
The first formal argument represents the global reference number for which
the variable block is being accessed. The second formal argument,
, represents a unique identifier for the caller.
caller_id
Enter_Shared_Varblk...
