Delphi 6 DLL problem

[Roland Smith]

Marco,

I don't know Delphi but here is a function from a .dll I wrote in C that
works. A software package we bought had been coded using STDCALL so I
created a wrapper .dll using WINAPI. The PB app calls my .dll which then
calls theirs.

DWORD WINAPI pbarm_init( LPSTR lpszApplName )
{
DWORD dwApplID;

dwApplID = arm_init(lpszApplName, "*", 0, 0, 0);

return dwApplID;
}

PowerBuilder External Declaration:

Function long pbarm_init(string lpszApplName) Library "pbarm.dll"
