I need to define a structure that is byte packed.
I was planning on using #pragma pack (1)
So when does the pragma pack end right after the first structure definition
or
at the end of the header file or until a new pragma pack is encountered...
This need to work for visual c++ as well as g++ (gnu cpp 3.3)

I'm told that "#pragma once" has made it into the ISO standard for
either C or C++. I can't find any reference to that anywhere. If
it's true, do any of you have a reference I can use?
Thanks...

PRAGMA:-Signifies that the statement is a pragma (compiler directive). Pragmas are processed at compile time, not at run time. They pass information to the compiler.
A pragma is an instruction to the Oracle compiler that tells it to do something. In this case you are telling Oracle to associate an error that you choose to a variable that you choose. This pragma must go in the declarative section of your block.
Types of PRAGMA...

If I use #pragma pack to byte align structures to non word size , will
this cause the program to run slightly slower if it is accessing and
setting non word aligned integers etc in the struct? Is there any
realignment going on silently underneath when the var is read and
written to memory?
