P5getservbyname - Implement Perl 5's getservbyname() and associated built-ins
use P5getservbyname; # exports getservbyname, getservbyport, getservent, setservent, endservent say getservbyport(25, "tcp", :scalar); # "smtp" my @result_byname = getservbyname("smtp"); my @result_byport = getservbyport(|@result_byname[3,4]);
This module tries to mimic the behaviour of the
getservbyname and associated functions of Perl 5 as closely as possible. It exports by default:
endservent getservbyname getservbyport getservent setservent
getservbyname NAME,PROTO getservbyport PORT,PROTO getservent setservent STAYOPEN endservent These routines are the same as their counterparts in the system C library. In list context, the return values from the various get routines are as follows: # 0 1 2 3 4 ( $name, $aliases, $port, $proto ) = getserv* (If the entry doesn't exist you get an empty list.) In scalar context, you get the name, unless the function was a lookup by name, in which case you get the other thing, whatever it is. (If the entry doesn't exist you get the undefined value.)
