_doprnt does not exist.  Well, at least not on my machine.  (Neither
does stdin->_flag.  One might be surprised how many programs use the
latter.  NNTP just broke, for instance.)

The reason there is no documentation is that it is an internal, private
function.  It implements the raw workings of `printf' based on a bunch
of private data fields in the `FILE' argument.

Chances are that whatever program you have that uses _doprnt actually
wants vsprintf.
