valid class?

Hello ,

I used to program in c++ several years before and totally out of touch now. I was trying to compile a small program. Please let me know whether it is meaningful.

#include <stdio.h>
#include <stdlib.h>
#include <string.h>

#ifdef AIX
#include <langinfo.h>
#endif

#include <sys/types.h>
#include <sys/timeb.h>
#include <time.h>

/* MQSeries headers */
#include <cmqc.h>
#include <cmqxc.h>

/*  testing headers  */
#include <time.h>

/* dummy function used as entry point to exit, only needed  AIX boxes */
void MQStart() {;}	/* dummy entry point */

void MQENTRY MQMDH001( PMQCXP     pChannelExitParams,
				       PMQCD      pChannelDefinition,
				       PMQLONG    pDataLength,
			           PMQLONG    pAgentBufferLength,
				       PMQBYTE    AgentBuffer,
				       PMQLONG    pExitBufferLength,
				       PMQPTR     pExitBufferAddr)

{
	char Channel_Logfile[] = "c:\\temp\\scylog.log";
	FILE * fp; 

    /* for test purposes */
    char TimeBuffer[100];
    struct tm *pNow=NULL;
    time_t MyTime;

    /* open the log file */
	fp = fopen(Channel_Logfile,"a+");

	pChannelExitParams->ExitResponse = MQXCC_OK;

	pChannelExitParams->Feedback = 0;

	switch( pChannelExitParams-> ExitReason )
	{
		case MQXR_INIT:
               MyTime=time(NULL);
               pNow=localtime(&MyTime);
               strftime(TimeBuffer, sizeof(TimeBuffer),
				   "\nScy exit called for INIT at %A %B %d, %Y at %I:%M %p\n", pNow);
			   fprintf(fp, "%s", TimeBuffer);
			   break;
		case MQXR_INIT_SEC:
               *pDataLength = 9;
	           pChannelExitParams->ExitResponse = MQXCC_SEND_SEC_MSG;
	           strncpy((char *)AgentBuffer, "WHOAREYOU\0", 10);
		       fprintf(fp,"Scy exit called for INIT_SEC, resp=%d, buff=%s\n", pChannelExitParams->ExitResponse, (char *)AgentBuffer);
			   break;
		case MQXR_SEC_MSG:
		       fprintf(fp,"Scy exit called for SEC_MSG, resp=%d, buff=%.10s\n", pChannelExitParams->ExitResponse, (char *)AgentBuffer);
               *pDataLength = 20;
	           pChannelExitParams->ExitResponse = MQXCC_SEND_SEC_MSG;

			   /******CHANGE userid/password in the following line:********/
	           strncpy((char *)AgentBuffer, "A000Userid  Password\0", 21);
			   /******END OF CHANGE userid/password: **********************/

		       fprintf(fp,"Scy exit called for SEC_MSG, resp=%d, buff=%.10s\n", pChannelExitParams->ExitResponse, (char *)AgentBuffer);
			   break;
		case MQXR_TERM:
			   fprintf(fp,"Scy exit called for TERM\n");
			   break;
		default:
			   fprintf(fp,"Scy exit called with invalid reason code: %d\n", pChannelExitParams-> ExitReason);
		       break;
	} /* switch */
	fclose(fp);
	return;      
} /* END OF void MQENTRY MQMDH001( 	 */

This doesn't have a main. So, doesn't compile. If I include a dummy main(){;}, What would happen? Should I call the method void MQENTRY MQMDH001() inside the main? Will it work? Please suggest.

Thanks

Hello,

Now that I learnt I need a dll from the above code, I don't think I require a main. But even for a dll, does the code above seem to do anything? Please reply.

Thanks
