P5getservbyname-0.0.6/

NAME

Raku port of Perl's getservbyname() and associated built-ins

SYNOPSIS

use P5getservbyname;
# exports getservbyname, getservbyport, getservent, setservent, endservent

say getservbyport(Scalar, 25, "tcp");   # "smtp"

my @result_byname = getservbyname("smtp");

my @result_byport = getservbyport(|@result_byname[3,4]);

DESCRIPTION

This module tries to mimic the behaviour of Perl's getservbyname and associated built-ins as closely as possible in the Raku Programming Language.

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.)

PORTING CAVEATS

This module depends on the availability of POSIX semantics. This is generally not available on Windows, so this module will probably not work on Windows.
