Hello,
Please Help me with programming arexx communication programm in C.
All what i need is send a rexx message (command) 'MM_Version' and get reply from programm for
this command, in my case a reply looks like 'VERSION: 1.0; RELEASE 10.0' (two
different deciminal string)
In simple arexx script i can do it very easy, like this:
/* Rexx Proggy */
Address 'MAILMANAGER'
MM_Version buf
echo buf.VERSION
echo buf.RELEASE
And now i need same result in my C programm. Please help me. I make some... but
i have no idea how to continue my work... i can't find any usefull documentation
about rexx programming on C.
#include <proto/exec.h>
#include <proto/dos.h>
#include <proto/rexxsyslib.h>
#include <string.h>
void main(void)
{
struct MsgPort *MyPort;
struct MsgPort *MyPutPort;
Forbid();
if (MyPutPort = FindPort("MAILMANAGER"))
{
Permit();
Printf("Port found!\n");
if (MyPort = CreatePort(NULL,0))
{
struct RexxMsg *MyMsg;
Printf("Port created!\n");
if (MyMsg = CreateRexxMsg(MyPort, NULL, "MAILMANAGER"))
{
UBYTE Command[] = {"MM_Version",NULL};
UBYTE *MyArgString;
Printf("Rexx message created!\n");
if (MyArgString = CreateArgstring(Command, strlen(Command)))
{
struct RexxMsg *MyReplyRexxMsg;
Printf("Arg string created!\n");
MyMsg->rm_Action = RXCOMM;
MyMsg->rm_Args[0] = (STRPTR)MyArgString;
PutMsg(MyPutPort, &MyMsg->rm_Node);
WaitPort(MyPort);
if (MyReplyRexxMsg = (struct RexxMsg *)GetMsg(MyPort))
{
Printf("Got reply message!\n");
if (IsRexxMsg(MyReplyRexxMsg))
Printf("Rexx Msg!\n");
else
Printf("Not a Rexx Msg!\n");
Printf("Buffer: %s\n", MyReplyRexxMsg->rm_Args[0]);
Printf("Buffer: %s\n", MyReplyRexxMsg->rm_Args[1]);
Printf("Buffer: %s\n", MyReplyRexxMsg->rm_Args[2]);
// rm_Args always contain my command or trash, nobody change it :(
}
DeleteArgstring(MyArgString);
}
else
Printf("Can't create arg string!\n");
DeleteRexxMsg(MyMsg);
}
else
Printf("Can't create RexxMsg!\n");
DeletePort(MyPort);
}
else
Printf("Can't creates ports!\n");
}
else
{
Permit();
Printf("Can't find port!\n");
}
}
How can i get a result from MAILMANAGER port? :)
Kind regards
