  1. Fix dtc_output read when interrupted by EINTR 

    The read() call may be interrupted by a signal, resulting in an EINTR error.
In this case, read() will return -1 and set errno to EINTR.
This is a common issue when dealing with I/O in a multi-process environment.

Check the error code returned by errno.
If it is EINTR, we can safely retry the read().
