Hello all,
I am considering using a C++ API for the new portable ca server
library. As I see it there are two primary concerns that must be
addressed:
1) Sites that use the new ca server lib must have a C++ compiler.
Most vendors are now releasing one compiler that eats both ANSI
C and C++. Otherwise under UNIX you can always use g++ as long
as any header file/library difficulties are sorted out. For vxWorks
it is reasonable to get g++ and configure it as a cross compiler.
Does tornado include a properly configured gnu C++ cross compiler?
2) There are many existing C codes which would like to export
EPICS process variables.
In this case a small C++ glue code could be created and this could be
used call the existing ANSI C code whoose function prototypes are
shrouded by "extern "C" {". There is also the possibility of creating
a C API which is a wrapper for the C++ API.
If the possibility of a C++ API for the new CA server causes you grief
please reply to this message so that we can make an informed decision.
Thanks
Jeff
