Hi Harry,
This is a bit complicated.

These are not Toolkit functions. These are effectively macros, that get
resolved at compile time to call the correct class or instance method
based on the static SOM class hierarchy. This hierarchy is defined in the
interface description language (idl) file for the class definition.
Runtime class replacements may alter the method that is finally called,
but this is transparent to your code.

It will not solve your problem but you need to understand that different
compilers use different calling conventions. The Watcom default is a
register based calling convention that suffixes external names with an
underscore. The VAC default is a register based convention that applies
no prefix or suffix characters The Microsoft C default is stack based and
prefixes external names with an underscore. Note that the underscore
prefix in your example is none of the above. It is just part of the macro
name.
To make code built with different tools interoperate, you need to use
modifiers such as cdecl and system in the function declarations so that
the compiler can generate the correct calling convention code. If you
look at the toolkit headers, you will see how this is done.
>Can anyone help me with this. Thanks for any information.
Since you never supplied snippets of the failing code or stated any goal
beyond getting a clean build of your code, I have to guess you are trying
to use WPS code in a PM application. That will not work. To proceed
further, you are going to have to explain what you are really trying to
do.
If you really want to do WPS programming, take a look at the WPS sample
code in the Toolkit. Reading about "Creating SOM Classes" in the WPS
Programming Guide will also be helpful.

Steven
