function Instance¶

static MemoryPool & Instance()

The process-wide singleton pool.

Return: Reference to the singleton MemoryPool.

    const MemoryPool & 
) =delete

function operator=¶

) =delete

function Allocate¶

std::shared_ptr< PinnedBuffer > Allocate(
    size_t size_bytes,
    bool page_locked =true
)

Return a buffer of at least size_bytes, reusing a cached one when possible.

Parameters:

• size_bytes Requested capacity in bytes.
• page_locked Whether a freshly allocated buffer is page-locked.
