Re: printf showing junk data in stdout

Scott,
RUN_ECDSTP is actually a CL program which in turn calls the C program.
Below are relevent code in this CL:

PGM PARM(&HOST &PORT &LIBNAME &LOCK)
DCL VAR(&HOST) TYPE(*CHAR) LEN(10)
DCL VAR(&PORT) TYPE(*CHAR) LEN(4)
DCL VAR(&LIBNAME) TYPE(*CHAR) LEN(10)
DCL VAR(&LOCK) TYPE(*CHAR) LEN(10)
DCL VAR(&C_HOST) TYPE(*CHAR) LEN(30)
DCL VAR(&C_PORT) TYPE(*CHAR) LEN(30)

CHGVAR VAR(&C_HOST) VALUE(&HOST)
CHGVAR VAR(&C_PORT) VALUE(&PORT)
CALL PGM(&LIBNAME/ECD_STP3) PARM(&C_HOST &C_PORT '50000')
ENDPGM



I'm still not sure if the CL call is the problem, because the data looks
ok in debug (See below for screen shot). It just not look right in
stdout.

The actual program is quite big. I used your version and call it from a
mark up CL and it works fine.

Hi Lim,

Sorry, I did not cut and paste the code correctly in my OP. Below

is

what the code looks like

I can't see anything wrong with your code, and indeed, I tried it on

my

own system, and did not have the problem you've described. However,
since the code you posted wasn't a complete program, I had to add some

code to make it work (maybe that makes it different)?

What Simon says is true, of course. But, I'm not sure that it applies

to your situation, since you stated that you were calling it with the
following command (this is a copy/paste from your message):

CALL PGM(*LIBL/RUN_ECDSTP) PARM('NOCC07QA' '5553' '*LIBL' UA_STP3)

Since all of your parms are literals on the command-line, and not
variables from another program, they should all be null-terminated
properly. And, indeed, when I ran your code, I didn't see any

garbage.

Here's the code I test with:


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


int get_time_stamp(char sString[])
{
time_t thetime;
struct tm *usetime;
char sTime[20];

time(&thetime);
usetime=localtime(&thetime);
sprintf(sTime,"%02d/",usetime->tm_mon+1);
sprintf(sTime+3,"%02d/",usetime->tm_mday);
sprintf(sTime+6,"%4u ", usetime->tm_year + 1900);
sprintf(sTime+11,"%02d:",usetime->tm_hour);
sprintf(sTime+14,"%02d:",usetime->tm_min );
sprintf(sTime+17,"%02d",usetime->tm_sec );
strcpy(sString,sTime);
return(1);
}


void
printThis(char *text)
{
char stime[20];

memset(stime, 0x0, sizeof(stime));
get_time_stamp(stime);
printf("%s %s\n", stime, text);
}


int main(int argc, char **argv) {

char printThisBuf[110];

sprintf(printThisBuf, "argv[0]->%s\n", argv[0]);
printThis(printThisBuf);

sprintf(printThisBuf, "argv[1]->%s\n", argv[1]);
printThis(printThisBuf);

sprintf(printThisBuf, "argv[2]->%s\n", argv[2]);
printThis(printThisBuf);

sprintf(printThisBuf, "argv[3]->%s\n", argv[3]);
printThis(printThisBuf);

return 0;
}
