formline PICTURE,LIST This is an internal function used by formats, though you may call it, too. It formats (see perlform) a list of values according to the contents of PICTURE, placing the output into the format output accumulator, $^A (or $ACCUMULATOR in English). Eventually, when a write is done, the contents of $^A are written to some filehandle. You could also read $^A and then set $^A back to "" . Note that a format typically does one formline per line of form, but the formline function i

getpeername SOCKET Returns the packed sockaddr address of the other end of the SOCKET connection. use Socket; $hersockaddr = getpeername(SOCK); ($port, $iaddr) = sockaddr_in($hersockaddr); $herhostname = gethostbyaddr($iaddr, AF_INET); $herstraddr = inet_ntoa($iaddr);

$^M By default, running out of memory is an untrappable, fatal error. However, if suitably built, Perl can use the contents of $^M as an emergency memory pool after die()ing. Suppose that your Perl were compiled with -DPERL_EMERGENCY_SBRK and used Perl's malloc. Then $^M = 'a' x (1 << 16); would allocate a 64K buffer for use in an emergency. See the INSTALL file in the Perl distribution for information on how to add custom C compilation flags when compiling perl. To discourage casual us

%SIG The hash %SIG contains signal handlers for signals. For example: sub handler { # 1st argument is signal name my($sig) = @_; print "Caught a SIG$sig--shutting down\n"; close(LOG); exit(0); } $SIG{'INT'} = \&handler; $SIG{'QUIT'} = \&handler; ... $SIG{'INT'} = 'DEFAULT'; # restore default action $SIG{'QUIT'} = 'IGNORE'; # ignore SIGQUIT Using a value of 'IGNORE' usually has the effect of ignoring the signal, except for the CHLD signal. See perlipc for mo

evalbytes EXPR evalbytes This function is like eval with a string argument, except it always parses its argument, or $_ if EXPR is omitted, as a string of bytes. A string containing characters whose ordinal value exceeds 255 results in an error. Source filters activated within the evaluated code apply to the code itself. This function is only available under the evalbytes feature, a use v5.16 (or higher) declaration, or with a CORE:: prefix. See feature for more information.
