tmpfile

POSIX-style tmpfile — open an anonymous temporary file and return the filehandle. The file is unlinked immediately.

Synopsis

my $fh = tmpfile();
print $fh "scratch\n";
seek $fh, 0, 0;

What you get back

An open read/write filehandle reference. There is no filename to hand out: the file is removed from the directory immediately after opening and exists only as long as $fh is open.

Examples

my $fh = tmpfile();
print $fh "line 1\n";
seek $fh, 0, 0;
my $line = <$fh>;                           # "line 1\n"

Edge cases

• On filesystems that refuse to unlink open files the file stays on disk until $fh is closed.

Differences from upstream

Fully compatible with upstream File::Temp 0.2312.

• tmpnam — returns only a name (or ($fh, $name) in list context).
