Salut Rémi,
The _mp_ prefixes are not really required, and I think
they are not defined for all functions in the standard TrnDll.
To use these functions from C, you can directly declare the
function with the name exported with the
!DEC$ATTRIBUTES DLLEXPORT attribute in the FORTRAN source. Due
to FORTRAN conventions, the name given is in capital letters, so
SETSTORAGEVARS
could do the trick in your case (instead of TRNSYSFUNCTIONS_mp_SETSTORAGEVARS).
I use the free tool from http://www.dependencywalker.com/ on
TRNDll.dll to find out.
The real question, as I may have mentioned before, is: why would
anyone who programs in C want to use these functions?
They were introduced 20 years ago for FORTRAN programmers to
mimic static arrays. I think you’re in for much less trouble if you
declare local, static arrays in your DLL and handle storage by yourself…

Objet : [TRNSYS-users] TR: trnsys.h problem with storage functions
Hi,
I’ve
read some posts talking about the missing storage functions in the trnsys.h
file, I tried to add them manually, writing :
extern "C" __declspec(dllimport) void
_cdecl TRNSYSFUNCTIONS_mp_SETSTORAGEVARS(double[],int,int[]);
extern "C" __declspec(dllimport) void
_cdecl TRNSYSFUNCTIONS_mp_SETSTORAGESIZE(int,int[]);
extern "C" __declspec(dllimport)
void _cdecl
TRNSYSFUNCTIONS_mp_GETSTORAGEVARS(double[],int,int[]);
in
the “Functions to access TRNSYS global
variables” and :
#define
setStorageVars
TRNSYSFUNCTIONS_mp_SETSTORAGEVARS
#define
setStorageSize
TRNSYSFUNCTIONS_mp_SETSTORAGESIZE
#define
getStorageVars
TRNSYSFUNCTIONS_mp_GETSTORAGEVARS
In
the “Short aliases for functions included in
module TrnsysFunctions + lowercase variants of kernel routines”
part of the trnsys.h file.
But
I still get this error message :
1>type896.obj : error LNK2019: symbole externe
non résolu __imp__TRNSYSFUNCTIONS_mp_SETSTORAGEVARS référencé dans la fonction
_TYPE896
1>C:\Program
Files\Trnsys16\UserLib\DebugDLLs\Type896Lib.dll : fatal error LNK1120: 1
externes non résolus
Do
you have any idea of how I could access to those storage functions ?
