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.
