JCuda.cudaFreeHost介绍

[英]Frees page-locked memory.

cudaError_t cudaFreeHost ( 
void* ptr )

Frees page-locked memory. Frees the memory space pointed to by hostPtr, which must have been returned by a previous call to cudaMallocHost() or cudaHostAlloc().
Note:

Note that this function may also return error codes from previous, asynchronous launches.
[中]释放页面锁定的内存

cudaError_t cudaFreeHost ( 
void* ptr )

释放页面锁定的内存。释放hostPtr指向的内存空间，该内存空间必须由先前对cudaMallocHost（）或cudaHostAlloc（）的调用返回。
注:
请注意，此函数还可能返回以前异步启动的错误代码。
