-Fri Jul 3 15:06:40 1998 Jarkko Hietaniemi <jhi@iki.fi>
-
- - Integrated IPC::SysV 1.03 to Perl 5.004_69.
-
-Change 142 on 1998/05/31 by <gbarr@pobox.com> (Graham Barr)
-
- - Changed SHMLBA from a constSUB to an XS sub as on some systems it is not
- a constant
- - Added a missing MODULE line to SysV.xs so ftok is defined in IPC::SysV
-
-Change 138 on 1998/05/23 by <gbarr@pobox.com> (Graham Barr)
-
- Applied patch from Jarkko Hietaniemi to add constats for UNICOS
-
- Reduced size of XS object by changing constant sub definition
- into a loop
-
- Updated POD to include ftok()
-
-Change 135 on 1998/05/18 by <gbarr@pobox.com> (Graham Barr)
-
- applied changes from Jarkko Hietaniemi <jhi@iki.fi> to add
- new constants and ftok
-
- fixed to compile with >5.004_50
-
- surrounded newCONSTSUB with #ifndef as perl now defines this itself

+
+ - Integrated IPC::SysV 1.03 to Perl 5.004_69.
+
+Change 142 on 1998/05/31 by <gbarr@pobox.com> (Graham Barr)
+
+ - Changed SHMLBA from a constSUB to an XS sub as on some systems it is not
+ a constant
+ - Added a missing MODULE line to SysV.xs so ftok is defined in IPC::SysV
+
+Change 138 on 1998/05/23 by <gbarr@pobox.com> (Graham Barr)
+
+ Applied patch from Jarkko Hietaniemi to add constats for UNICOS
+
+ Reduced size of XS object by changing constant sub definition
+ into a loop
+
+ Updated POD to include ftok()
+
+Change 135 on 1998/05/18 by <gbarr@pobox.com> (Graham Barr)
+
+ applied changes from Jarkko Hietaniemi <jhi@iki.fi> to add
+ new constants and ftok
+
+ fixed to compile with >5.004_50
+
+ surrounded newCONSTSUB with #ifndef as perl now defines this itself

-IPC::SysV - SysV IPC constants
-
-=head1 SYNOPSIS
-
- use IPC::SysV qw(IPC_STAT IPC_PRIVATE);
-
-=head1 DESCRIPTION
-
-C<IPC::SysV> defines and conditionally exports all the constants
-defined in your system include files which are needed by the SysV
-IPC calls. Common ones include
-
- IPC_CREATE IPC_EXCL IPC_NOWAIT IPC_PRIVATE IPC_RMID IPC_SET IPC_STAT
- GETVAL SETVAL GETPID GETNCNT GETZCNT GETALL SETALL
- SEM_A SEM_R SEM_UNDO
- SHM_RDONLY SHM_RND SHMLBA
-
-and auxiliary ones
-
- S_IRUSR S_IWUSR S_IRWXU
- S_IRGRP S_IWGRP S_IRWXG
- S_IROTH S_IWOTH S_IRWXO
-
-but your system might have more.
-
-=over 4
-
-=item ftok( PATH, ID )
-
-Return a key based on PATH and ID, which can be used as a key for
-C<msgget>, C<semget> and C<shmget>. See L<ftok>

+=head1 NAME
+
+IPC::SharedMem - SysV Shared Memory IPC object class
+
+=head1 SYNOPSIS
+
+ use IPC::SysV qw(IPC_PRIVATE S_IRUSR S_IWUSR);
+ use IPC::SharedMem;
+
+ $shm = IPC::SharedMem->new(IPC_PRIVATE, 8, S_IRWXU);
+
+ $shm->write(pack("S", 4711), 2, 2);
+
+ $data = $shm->read(0, 2);
+
+ $ds = $shm->stat;
+
+ $shm->remove;
+
+=head1 DESCRIPTION
+
+A class providing an object based interface to SysV IPC shared memory.
+
+=head1 METHODS
+
+=over 4
+
+=item new ( KEY , SIZE , FLAGS )
+
+Creates a new shared memory segment associated with C<KEY>. A new
+segment is created if
+
+=over 4
+
+=item *
+
+C<KEY> is equal to C<IPC_PRIVATE>
+
+=item *
+
+C<KEY> does not already have a shared memory segment associated
+with it, and C<I<FLAGS> & IPC_CREAT> is true.
+
+=back
+
+On creation of a new shared memory segment C<FLAGS> is used to
+set the permissions. Be careful not to set any flags that the
+Sys V IPC implementation does not allow: in some systems setting
+execute bits makes the operations fail.
+
+=item id
+
+Returns the shared memory identifier.
+
+=item read ( POS, SIZE )
+
+Read C<SIZE> bytes from the shared memory segment at C<POS>. Returns
+the string read, or C<undef> if there was an error. The return value
+becomes tainted. See L<shmread>.
+
+=item write ( STRING, POS, SIZE )
+
+Write C<SIZE> bytes to the shared memory segment at C<POS>. Returns
+true if successful, or false if there is an error. See L<shmwrite>.
+
+=item remove
+
+Remove the shared memory segment from the system or mark it as
+removed as long as any processes are still attached to it.
+
+=item is_removed
+
+Returns true if the shared memory segment has been removed or
+marked for removal.
+
+=item stat
+
+Returns an object of type C<IPC::SharedMem::stat> which is a sub-class
+of C<Class::Struct>. It provides the following fields. For a description
+of these fields see you system documentation.
+
+ uid
+ gid
+ cuid
+ cgid
+ mode
+ segsz
+ lpid
+ cpid
+ nattach
+ atime
+ dtime
+ ctime
+
+=item attach ( [FLAG] )
+
+Permanently attach to the shared memory segment. When a C<IPC::SharedMem>
+object is attached, it will use L<memread> and L<memwrite> instead of
+L<shmread> and L<shmwrite> for accessing the shared memory segment.
+Returns true if successful, or false on error. See L<shmat>.
+
+=item detach
+
+Detach from the shared memory segment that previously has been attached
+to. Returns true if successful, or false on error. See L<shmdt>.
+
+=item addr
+
+Returns the address of the shared memory that has been attached to in a
+format suitable for use with C<pack('P')>. Returns C<undef> if the shared
+memory has not been attached.

+
+IPC::SysV - System V IPC constants and system calls
+
+=head1 SYNOPSIS
+
+ use IPC::SysV qw(IPC_STAT IPC_PRIVATE);
+
+=head1 DESCRIPTION
+
+C<IPC::SysV> defines and conditionally exports all the constants
+defined in your system include files which are needed by the SysV
+IPC calls. Common ones include
+
+ IPC_CREATE IPC_EXCL IPC_NOWAIT IPC_PRIVATE IPC_RMID IPC_SET IPC_STAT
+ GETVAL SETVAL GETPID GETNCNT GETZCNT GETALL SETALL
+ SEM_A SEM_R SEM_UNDO
+ SHM_RDONLY SHM_RND SHMLBA
+
+and auxiliary ones
+
+ S_IRUSR S_IWUSR S_IRWXU
+ S_IRGRP S_IWGRP S_IRWXG
+ S_IROTH S_IWOTH S_IRWXO
+
+but your system might have more.
+
+=over 4
+
+=item ftok( PATH )
+
+=item ftok( PATH, ID )
+
+Return a key based on PATH and ID, which can be used as a key for
+C<msgget>, C<semget> and C<shmget>. See L<ftok>.
+
+If ID is omitted, it defaults to C<1>. If a single character is
+given for ID, the numeric value of that character is used.
+
+=item shmat( ID, ADDR, FLAG )
+
+Attach the shared memory segment identified by ID to the address
+space of the calling process. See L<shmat>.
+
+ADDR should be C<undef> unless you really know what you're doing.
+
+=item shmdt( ADDR )
+
+Detach the shared memory segment located at the address specified
+by ADDR from the address space of the calling process. See L<shmdt>.
+
+=item memread( ADDR, VAR, POS, SIZE )
+
+Reads SIZE bytes from a memory segment at ADDR starting at position POS.
+VAR must be a variable that will hold the data read. Returns true if
+successful, or false if there is an error. memread() taints the variable.
+
+=item memwrite( ADDR, STRING, POS, SIZE )
+
+Writes SIZE bytes from STRING to a memory segment at ADDR starting at
+position POS. If STRING is too long, only SIZE bytes are used; if STRING
+is too short, nulls are written to fill out SIZE bytes. Returns true if
+successful, or false if there is an error.
