NAME SYNOPSIS ABSTRACT In Practice SEE ALSO NAME Encode::Unicode::UTF7 -- UTF-7 encoding SYNOPSIS use Encode qw/encode decode/; $utf7 = encode("UTF-7", $utf8); $utf8 = decode("UTF-7", $ucs2); ABSTRACT This module implements UTF-7 encoding documented in RFC 2152. UTF-7, as its name suggests, is a 7-bit re-encoded version of UTF-16BE. It is designed to be MTA-safe and expected to be a standard way to exchange Unicoded mails via mails. But with the advent of UTF-8 and 8-bit compliant MTAs, UTF

read FILEHANDLE,SCALAR,LENGTH,OFFSET read FILEHANDLE,SCALAR,LENGTH Attempts to read LENGTH characters of data into variable SCALAR from the specified FILEHANDLE. Returns the number of characters actually read, 0 at end of file, or undef if there was an error (in the latter case $! is also set). SCALAR will be grown or shrunk so that the last character actually read is the last character of the scalar after the read. An OFFSET may be specified to place the read data at some place in the string o

IO::Handle->output_field_separator( EXPR )

$[ This variable stores the index of the first element in an array, and of the first character in a substring. The default is 0, but you could theoretically set it to 1 to make Perl behave more like awk (or Fortran) when subscripting and when evaluating the index() and substr() functions. As of release 5 of Perl, assignment to $[ is treated as a compiler directive, and cannot influence the behavior of any other file. (That's why you can only assign compile-time constants to it.) Its use is hig

time Returns the number of non-leap seconds since whatever time the system considers to be the epoch, suitable for feeding to gmtime and localtime. On most systems the epoch is 00:00:00 UTC, January 1, 1970; a prominent exception being Mac OS Classic which uses 00:00:00, January 1, 1904 in the current local time zone for its epoch. For measuring time in better granularity than one second, use the Time::HiRes module from Perl 5.8 onwards (or from CPAN before then), or, if you have gettimeofday(2

List Operators (Rightward) On the right side of a list operator, the comma has very low precedence, such that it controls all comma-separated expressions found there. The only operators with lower precedence are the logical operators "and" , "or" , and "not" , which may be used to evaluate calls to list operators without the need for parentheses: open HANDLE, "< :utf8", "filename" or die "Can't open: $!\n"; However, some people find that code harder to read than writing it with parentheses

shmctl ID,CMD,ARG Calls the System V IPC function shmctl. You'll probably have to say use IPC::SysV; first to get the correct constant definitions. If CMD is IPC_STAT , then ARG must be a variable that will hold the returned shmid_ds structure. Returns like ioctl: undef for error; "0 but true" for zero; and the actual return value otherwise. See also SysV IPC in perlipc and IPC::SysV documentation. Portability issues: shmctl in perlport.
