NAME

P5getservbyname - Implement Perl 5's getservbyname() and associated built-ins

SYNOPSIS

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]);

DESCRIPTION

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

ORIGINAL PERL 5 DOCUMENTATION

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.)
