Can you post a code fragment (even if it does not work) showing what you
want to achieve?

If C preprocessing is supported in P4, including P4-16, is the P4-16
"header" possible to be typedefed?  I am not sure what the type is because
the header is in the P4 library.  If a C preprocessor allows any C type such
as "int" to be typdefed, why not the P4-16 header?

 

Thanks,

 

Hemant
