tmpnam

POSIX-style tmpnam - in scalar context a candidate filename in the system temp directory; in list context a created file with its filehandle.

תקציר

my $name         = tmpnam();                # scalar: just a name
my ($fh, $name)  = tmpnam();                # list: creates the file

מה מוחזר

In scalar context a filename string in the system temp directory that does not exist at the moment of the call - there is still a race between picking it and opening it, so prefer tempfile. In list context, a freshly created file is returned along with its filehandle.

דוגמאות

use File::Temp qw/ tmpnam /;
my ($fh, $name) = tmpnam();                 # race-free file creation

מקרי קצה

• Scalar context does not create a file - callers must open the name themselves and accept the race.
