I'm trying to make a program that uses forkpty(), then runs sh in the
child process, and then writes to the child using streams. But it
doesn't work! It hangs on the wait() call; apparently the child never
sees the "exit\n".
#include <unistd.h>
#include <sys/types.h>
#include <stdio.h>
main()
{
int fd;
pid_t pid;
pid = forkpty (&fd, 0, 0, 0);
if (pid == 0) {
execlp ("sh", "sh", (void *)0);
_exit (1);
} else if (pid == -1) {
exit (1);
} else {
FILE *F;
F = fdopen (fd, "w");
fprintf (F, "exit\n");
fflush (F);
wait (0);
}
exit (0);
}
