Hello,
when you call system() more than 98 times you get the following message.
0

........until..
98
(G:\watchdog\pars\tt.exe 1000) In cygwin_except_handler
(G:\watchdog\pars\tt.exe 1000) Exception trapped!

(G:\watchdog\pars\tt.exe 1000) frame 1: sp = 0x240EA5C, pc = 0x77FA4512
.... and os on.....

The following Program produces that error:
#include <stdio.h>
main()
{  
  char syscmd[124];
  int i=0;

  for(i=0;i<1024;i++) {
    sprintf(syscmd,"echo %d",i);
    system(syscmd);
  }
}

Has somebody a solution to this Problem

With regards

Michael Emrich
