If +ERRFH is '', or the same as RDRFH, then STDOUT and STDERR of the child are +on the same file handle. + +If WTRFH begins with ">&", then WTRFH will be closed in the parent, and +the child will read from it directly. if RDRFH or ERRFH begins with +">&", then the child will send output directly to that file handle. In both +cases, there will be a dup(2) instead of a pipe(2) made. + +All caveats from open2() continue to apply. See L<open2> for details. + |
