%description
|
|
File locking in Perl is usually done using the 'flock' function.
|
|
Unfortunately, this only allows locks on whole files and is often
|
|
implemented in terms of the the flock(2) manpage system function which has
|
|
some shortcomings (especially concerning locks on remotely mounted file
|
|
systems) and slightly different behaviour than the fcntl(2) manpage.
|
|
|
|
Using this module file locking via the fcntl(2) manpage can be done
|
|
(obviously, this restricts the use of the module to systems that have a the
|
|
fcntl(2) manpage system call). Before a file (or parts of a file) can be
|
|
locked, an object simulating a flock structure, containing information in a
|
|
binary format to be passed to the fcntl(2) manpage for locking requests,
|
|
must be created and its properties set. Afterwards, by calling the the
|
|
lock() manpage method a lock can be set and removed or it can be determined
|
|
if and which process currently holds the lock.
|
|
|
|
File::FcntlLock (or its alias File::FcntlLock::XS) uses a shared library,
|
|
build during installation, to call the the fcntl(2) manpage system function
|
|
directly. If this is unsuitable there are two alternatives,
|
|
File::FcntlLock::Pure and File::FcntlLock::Inline. Both call the Perl
|
|
'fcntl' function instead and use Perl code to assemble and disassemble the
|
|
structure. For this at some time the (system-dependent) binary layout of
|
|
the flock structure must have been determined via a program written in C.
|
|
The difference between File::FcntlLock::Pure and File::FcntlLock::Inline is
|
|
that for the former this happened when the package is installed while for
|
|
the latter it is done each time the package is loaded (e.g., with 'use').
|
|
Thus, for File::FcntlLock::Inline to work a C compiler must be available.
|
|
There are some minor differences in the functionality and the behaviour on
|
|
passing the method for locking invalid arguments to be described below.
