Re: [TRNSYS-users] Calling MESSAGES function in C++

Add to Trnsys.h :

extern "C" __declspec(dllimport) void _cdecl MESSAGES(int* errorCode,char* message, char* severity, int* unitNo, int* typeNo, int n, int m);

Use :

char Message[800];

strcpy(Message, "Its before 10");

char Severity[10];

strcpy(Severity, "NOTICE");

int errCode = 1;

int Unit = 4; // put your unit number here – typically info[0]

int Type = 6; // put your type number here - typically info[1]

if (time < 10)

messages(&errCode, Message, Severity, &Unit, &Type, strlen(Message), strlen(Severity));

Severity can be « NOTICE », « WARNING » or «ERROR»

The ‘trick’ is that FORTRAN passes string lengths as additional, hidden arguments – you have to add them at the end of any function using one or several strings as an argument, in the same order as the arguments (one per string passed). (See Trnsys.h or TrnsysFunctions.f90 if the function is missing in Trnsys.h for function prototypes).

Objet : [TRNSYS-users] Calling MESSAGES function in C++

Hello all,
I am trying to generate list file warning messages in my C++-compiled Type. According to the comments in the exported type C++ template, you use the "MESSAGES" function, which is not recognized by C++ (and I don't see it in Trnsys.h):

// REPORT ANY PROBLEMS THAT HAVE BEEN FOUND USING CALLS LIKE THIS:
MESSAGES(-1,'put your message here','MESSAGE',IUNIT,ITYPE)

In the Ch 08 Programmer's Guide, the syntax is:

call Messages(errorCode,message,severity,unitNo,typeNo)

...but that is for Fortran. Does anyone know how to do it in C++?

Thanks,

Eric
