I am unsure how to define a couple of paramter types for a DLL.

From ????.H

int FUNCTYPE direct_transfer(char far *target);

char * FUNCTYPE CKTimeString(char *stringbuf, ULONG cktime);

Is the following correct?

INT PASCAL direct_transfer(LPACHAR)

LPACHAR PASCAL CKTimeString(LPACHAR, ULONG)

or is this correct?

INT PASCAL direct_transfer(LPACHAR)

LPACHAR PASCAL CKTimeString(ACHAR, ULONG)

I am unsure about the difference between the following

char *

char far *

are these both pointers or not?

Jim,

Both the PASCAL calling sequence and the far pointer data type are remanents of the 16-bit Windows world and are no longer used in 32-bit Windows.

If any of the "char *" parameters are suppose to be null terminated strings, I would declare those as LPASTR. The problem is "char *" can either mean the pointer to a buffer of an array of characters, or it can mean a pointer to a null terminated string of characters.

So your declarations like this:

INT STDCALL direct_transfer(LPACHAR)

LPACHAR STDCALL CKTimeString(LPACHAR, ULONG)

are the closest. It is hard to say which of the LPACHAR's should really be LPASTR's without a description of what the function expects.

Great and thanks Pat, I will set them all as LPACHAR and see if everything works.
