Convert C Prototype to RPG

[LMoore]

I need to interface our payroll program with Vertex Q Series payroll tax software. The Vertex functions are written in C and our payroll program is in RPG. I am not proficient in the C language so I'm struggling to prototype the functions in my RPG program. Here's an example:

PREFIX int POSTFIX VprtXML(tVprtConn lConnHdl,
void **pSession,
char *XmlBuf,
char *XmlResult,
long *pResultSize);

Here's what I tried (I hope I'm on the right track) but the 2nd parameter is not correct. What is the proper way to define the "void **pSession" parm? Do the others look correct?


D VprtXML PR EXTPROC(*CWIDEN:'VprtXML')
D pConn * value options(*string)
D pSession * value options(*string)
D pXmlBuf * value options(*string)
D pXmlResult * value options(*string)
D pResultSize 10I 0


Thanks,

Larry
