RE: structs and SNL

[Mark Rivers <rivers@cars.uchicago.edu>]

You must escape declarations of variables with types like struct, they are not known types to SNL.

If you "escape to C" the .h with "%%" then you'll have to do the same with your struct declaration.

cc-ing tech-talk for further comments from others.

Hi Michael,
I think that I understand reentrant to mean (in part) that variables in SNL and C-code
can be related.  Assuming that is true, then I'm attempting to implement the section
"Variable Modification for Reentrant Option".  My C code reads our database and I
would like to use some of the variables from there in an entry block of a particular
state.

So, in the top-level declarations I define a number a variables which have the same
declaration as those in a struct in a header which I include in the top-level with %%
escape:

option +r;

%%#include "MICEStates.h"

char name[50];
...

If I understand the documentation, I should be able to do:
struct PV *cPV;
where PV is the name of my struct in the header file (I also tried UserVar, as
in the example).  However, at compile time, I get the error "type specifier".
This error follows the "struct" statement wherever I put it in the code.

Can you tell me what I'm doing incorrectly?
Thank you.
