Dear all,
Somewhere in my boundary element solver I have a console progress bar
which prints to screen the progress of an operation.
It looks like this:
INFO : 50% [------------> ]
The function is very simple:
//i is the current iteration number
//n is the total number of iterations
void progressBar(int x, int n)
{
if ( x % (n/100) != 0 ) return;
// Calculate the ratio of complete-to-incomplete.
float ratio = x/(float)n;
int c = ratio * 80
// Show the percentage complete.
printf("INFO :\t%3d%% [", (int)(ratio*100) );
// Show the load bar.
for (int x=0; x<c-1; x++)
printf("-");
printf(">");
for (int x=c; x<pBarWidth; x++)
printf(" ");
// ANSI Control codes to go back to the
// previous line and clear it.
printf("]\n\033[F\033[J");
}
My problem is that the progress bar doesn't print to screen as soon as I
call the PetscInitialize() function (it works fine otherwise).
I tried to play with fflush(stdout) commands without any success.
Any ideas ?
Thanks,
Thomas Leissing
