Archivo: syn-read.c Proyecto: firehazard/PintosOS

void
test_main (void) 
{
  pid_t children[CHILD_CNT];
  int fd;

  CHECK (create (filename, sizeof buf), "create \"%s\"", filename);
  CHECK ((fd = open (filename)) > 1, "open \"%s\"", filename);
  random_bytes (buf, sizeof buf);
  CHECK (write (fd, buf, sizeof buf) > 0, "write \"%s\"", filename);
  msg ("close \"%s\"", filename);
  close (fd);

  exec_children ("child-syn-read", children, CHILD_CNT);
  wait_children (children, CHILD_CNT);
}

Ejemplo n.º 2

Archivo: syn-write.c Proyecto: Kevin12353/sysu-os-team4

void
test_main (void) 
{
  pid_t children[CHILD_CNT];
  int fd;

  CHECK (create (file_name, sizeof buf1), "create \"%s\"", file_name);

  exec_children ("child-syn-wrt", children, CHILD_CNT);
  wait_children (children, CHILD_CNT);

  CHECK ((fd = open (file_name)) > 1, "open \"%s\"", file_name);
  CHECK (read (fd, buf1, sizeof buf1) > 0, "read \"%s\"", file_name);
  random_bytes (buf2, sizeof buf2);
  compare_bytes (buf1, buf2, sizeof buf1, 0, file_name);
}
