While run my last test code, every time comes one connection, there
are 3 handle leak( I monited it by Process Explorer( from
www.sysinternals.com)), one is the chile process's handle, one is of
"Section \BaseNamedObjects\cygwin1S5-9770bb4ddbd85dca\cygpid.xxxx",
the other one is of \Device\Afd.
I mean is there any other leak with those handles.
Simple code like the following will not leak anything:
#include <unistd.h>
#include <stdio.h>
int main(void)
{
pid_t pid = fork();
while(1)
{
if ( pid == 0 )
{
sleep(5);
printf("Child: %d ended\n", getpid());
return 0;
}
else if ( pid > 0 )
{
printf("New process forked.\n");
sleep(10);
}
}
}
