Those are portable entries. The ones you list from COM interface are Windows-specific. They are in fact variations of GetA/SetA only with different params.
Their definitions can be derived from the COM interface. However, working with the struct J is as easy. What are your concerns? As you may have realized working with intput/output streams are only necessary if you wish to emulate session, and can be done without for regular call-based processing. > From: Yuvaraj Athur Raghuvir <[EMAIL PROTECTED]> > > This is what I have with me (from jlib.h in jfe) > > J _stdcall JInit(); /* init instance */ > void _stdcall JSM(J jt, void*callbacks[]); /* set callbacks */ > int _stdcall JDo(J jt,C*); /* run sentence */ > C* _stdcall JGetLocale(J jt); /* get locale */ > int _stdcall JFree(J jt); /* free instance */ > A _stdcall JGetA(J jt,I n,C* name); /* get 3!:1 from name */ > I _stdcall JSetA(J jt,I n,C* name,I x,C* d);/* name=:3!:2 data */ > > What are the corresponding signatures for SetB, GetB, SetM, GetM and the > rest of the APIs that the dll exposes? > > I refer to GetM since that is used in the dll.ijs code. > > I am working on windows. > > ~Yuva > > > On Thu, Nov 6, 2008 at 12:17 PM, Raul Miller wrote: > > > On Thu, Nov 6, 2008 at 3:00 PM, Yuvaraj Athur Raghuvir > > wrote: > > > 1) I miss the entire list of calls I can make to the JDLL (including > > > signature).
