Parameters

sizeInBytes int

The allocation size in bytes. 分配大小，单位为字节。

CudaPinnedMemory(int, CudaPinnedMemoryAllocationFlags)

Allocates pinned host memory with explicit CUDA flags. 使用显式 CUDA 标志分配 pinned host memory。

public CudaPinnedMemory(int sizeInBytes, CudaPinnedMemoryAllocationFlags flags)

Parameters

sizeInBytes int

The allocation size in bytes. 分配大小，单位为字节。

flags CudaPinnedMemoryAllocationFlags

The pinned-memory allocation flags. pinned memory 分配标志。
