Dear Madam/Sir,
At present time, I port IOC codes from VxWorks to LynxOS/x86 platform.
I emulate VxWorks calls by LynxOS features.
I attach the list emulated VxWorks calls to end this letter. I do not
emulate some libraries supports BSP calls. Because this functions would be
executed by UNIX drivers. I do not compile iocCore completely yet.
Now I port data base, and I find difficulty in doing 'symbol table
subroutine library'.
EPICS uses following symLib calls:
1) symFindByNameEPICS(...) is equal to symFindByName(...)
2) symFindByNameAndTypeEPICS(..)is equal to symFindByNameAndType(...)
3) symFindByValue(...)
4) symTblCreate(...)
5) symAdd(...)
6) symRemove(...)
EPICS uses sysSymTbl as pointer to symbol table. I do not find <creation
of symbol table> in IOC codes.
1-st question :
---------------
IOC uses system symbol table which spawned by
tornado/target/config/mv167/symTabl.c
Is it correct?
2-nd question:
----------------
How can search a pointer (or address) this symbol table in vxWorks?
I guess that I can read all SYMBOL structures from this table and create
area with same structure in iocCore. This area will contain only EPICS
entries from symbol table.
So, tornado/target/config/mv167/symTabl.c contains
SYMBOL standTbl[2424] { ... ,};
vxWorks uses definitions
typedef SYMTAB *SYMBAB_ID;
SYMBAB_ID sysSymTbl;
Please, explain , is the pointer of standTbl disposed in struct
symtab SYMTAB?
If you will interest this IOC development at LynxOS, I will glad to
transfer this codes to you. And I will hear your comments about this work.
Thanks.
Best Regards,
Tatiana
