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