类名称：JCuda
方法名：cudaFree

JCuda.cudaFree介绍

[英]Frees memory on the device.

cudaError_t cudaFree ( 
void* devPtr )

Frees memory on the device. Frees the memory space pointed to by devPtr, which must have been returned by a previous call to cudaMalloc() or cudaMallocPitch(). Otherwise, or if cudaFree(devPtr) has already been called before, an error is returned. If devPtr is 0, no operation is performed. cudaFree() returns cudaErrorInvalidDevicePointer in case of failure.
Note:

Note that this function may also return error codes from previous, asynchronous launches.
[中]释放设备上的内存

cudaError_t cudaFree ( 
void* devPtr )

释放设备上的内存。释放devPtr指向的内存空间，该内存空间必须由上一次调用cudaMalloc（）或cudamalocpatch（）返回。否则，或者如果之前已经调用过cudaFree（devPtr），则返回一个错误。如果devPtr为0，则不执行任何操作。失败时，cudaFree（）返回cudaErrorInvalidDevicePointer。
注:
请注意，此函数还可能返回以前异步启动的错误代码。
