[ptp-user] eclipse console eats output

[Christoph Pospiech <Christoph.Pospiech@xxxxxxxxxx>]

Hi,

I stripped this down to a serial program with a serial run configuration. In my 
understanding I may have stripped off all PTP parts. Hence this mailing list 
may be the wrong place. If so, where should I post it instead ? Or any other 
hints or comments ?

If I start the program MPI_Output as detailed below in a C/C++ run 
configuration with arguments "4 1", I see the following output in the console 
window.

 11 Bytes written.
 11 Bytes written.
 11 Bytes written.
 11 Bytes written.
abcdefghij

As you notice, there is only one copy of "abcdefghij". I would expect four of 
them, as I see when starting the same executable in an ordinary bash.

cp@sirius:~/bench/DKRZ/MPI_Output/Debug_local$ pwd
/home/cp/bench/DKRZ/MPI_Output/Debug_local
cp@sirius:~/bench/DKRZ/MPI_Output/Debug_local$ ls
helloa.d  helloa.o  makefile  MPI_Output  objects.mk  sources.mk  subdir.mk
cp@sirius:~/bench/DKRZ/MPI_Output/Debug_local$ ./MPI_Output 4 1
abcdefghij 11 Bytes written.
abcdefghij 11 Bytes written.
abcdefghij 11 Bytes written.
abcdefghij 11 Bytes written.
cp@sirius:~/bench/DKRZ/MPI_Output/Debug_local$

Here is the program.
#include <stdio.h>
#include <stdlib.h>
#include <unistd.h>

char buf[] = "abcdefghij";

int main(int argc, char* argv[]) {
	int num_bytes_written;
	int num_repeats = 1;
	int print_num_bytes = 0;
	int i;

    /* Inspect the command line for arguments */
    if ( argc > 1 ) {
    	num_repeats = atoi(argv[1]);
    }
    if ( argc > 2 ) {
    	print_num_bytes = atoi(argv[2]);
    }

    for (i=0; i<num_repeats; i++) {
    	if (0>(num_bytes_written = write(1, buf, sizeof(buf)) )) {
    		perror("Error in writing buffer: ");
    	} else if (print_num_bytes) {
    		fprintf(stderr," %d Bytes written.\n", num_bytes_written);
    	}
    }
	return EXIT_SUCCESS;
}
