Sorry about the last message, I had a different ID set up so when I sent in
replies nothing was showing up! Now you have the latest code which should
work! The passing of a pointer to the RPG program is what I am questioning.
If you actually want to send in the value use the following
decimal(10,0) len;
len = *(decimal(10,0)*)argv[2];

Here is the code that should work. (Sorry had the wrong declaration for the
decimal pointer.)
#include <stdio.h>
#include <string.h>
#include <decimal.h>
#include <stdlib.h>
#pragma linkage(RGTRIGCNTL,OS)
void RGTRIGCNTL(char *, decimal(10,0)*);
int main(int argc, char **argv)
{
decimal (10,0) *len;
len = (decimal(10,2)*)argv[2];
RGTRIGCNTL(argv[1],len);
}
I assume you are passing a decimal into the program and are sending a
pointer to the RPG program?? If no you need to get the contents of the
argv[2] parameter and pass as a value.

First the code:
*#include <stdio.h>*
*#include <string.h>*
*#include <decimal.h>
#include <stdlib.h>
typedef void RGTRIGCNTL(char[80], decimal(10,0));
#pragma linkage(RGTRIGCNTL,fetchable)
int main(int argc, char *argv[])
{
char *triggerInfo;
decimal (10,0) triggerLen;
triggerInfo = argv[1];
triggerLen = argv[2];
RGTRIGCNTL(triggerInfo, &triggerLen);
}*
*What's going on: trying to write a small C program to attach to file
triggers.*
Problems:
pragma linkage won't allow 'OS' for a parameter. Everything I've read
indicates that's what I want. The only "ID' compiler didn't barf on is
'fetchable', which is why its there.
It compiles, but nothing happens when I try to step into RGTRIGCNTL.
The Dev box is V5R4 (long story).
The questions:
Why can't I use 'OS' in linkage? Why isn't my program getting called?
The last time I wrote a C program was in college, a looong time ago.
