The SyncSharedMemory class

(PECL sync >= 1.1.0)

はじめに

A cross-platform, native, consistent implementation of named shared memory objects.

Shared memory lets two separate processes communicate without the need for complex pipes or sockets. There are several integer-based shared memory implementations for PHP. Named shared memory is an alternative.

Synchronization objects (e.g. SyncMutex) are still required to protect most uses of shared memory.

class SyncSharedMemory {

/* メソッド */

public function __construct(string $name, int $size)

public function first(): bool

public function read(int $start = 0, int $length = ?)

public function size(): int

public function write(string $string = ?, int $start = 0)

}

SyncSharedMemory::__construct — Constructs a new SyncSharedMemory object
SyncSharedMemory::first — Check to see if the object is the first instance system-wide of named shared memory
SyncSharedMemory::read — Copy data from named shared memory
SyncSharedMemory::size — Returns the size of the named shared memory
SyncSharedMemory::write — Copy data to named shared memory
