setvbuf
$fh
->setvbuf(params
)
Takes the same parameters as the C function setvbuf(3)
and uses the C function to
set the buffering policy for the FileHandle.
The following additional FileHandle methods act as front-ends for the corresponding built-in Perl functions (see the O’Reilly book Programming Perl or the perlfunc manpage for more details):
The next group of FileHandle methods correspond to Perl special variables (see Programming Perl or the perlvar manpage):

Finally, the following methods are useful:
$
fh
->print
See Perl’s built-in print
function.
$
fh
->printf
See Perl’s built-in printf
function.
$
fh
->getline
Works like Perl’s <FILEHANDLE>
construct,
except that it can be safely called in an array context (but
it still returns just one line).
$
fh
->getlines
Works like Perl’s <FILEHANDLE>
construct when
called in an array context to read all remaining lines in a
file.
