       *  The child inherits copies of the parent’s set of open file descrip-         tors.   Each  file  descriptor  in the child refers to the same open          file description (see open(2)) as the corresponding file descriptor          in  the parent.  This means that the two descriptors share open file          status flags, current file offset, and signal-driven I/O attributes          (see the description of F_SETOWN and F_SETSIG in fcntl(2)).
