cudaError_t cudaMemset3D ( struct cudaPitchedPtr  pitchedDevPtr,
int  value,
struct cudaExtent  extent 

Initializes each element of a 3D array to the specified value value. The object to initialize is defined by pitchedDevPtr. The pitch field of pitchedDevPtr is the width in memory in bytes of the 3D array pointed to by pitchedDevPtr, including any padding added to the end of each row. The xsize field specifies the logical width of each row in bytes, while the ysize field specifies the height of each 2D slice in rows.

The extents of the initialized region are specified as a width in bytes, a height in rows, and a depth in slices.

Extents with width greater than or equal to the xsize of pitchedDevPtr may perform significantly faster than extents narrower than the xsize. Secondarily, extents with height equal to the ysize of pitchedDevPtr will perform faster than when the height is shorter than the ysize.

This function performs fastest when the pitchedDevPtr has been allocated by cudaMalloc3D().

pitchedDevPtr - Pointer to pitched device memory
value - Value to set for each byte of specified memory
extent - Size parameters for where to set device memory (width field in bytes)
cudaSuccess, cudaErrorInvalidValue, cudaErrorInvalidDevicePointer
Note that this function may also return error codes from previous, asynchronous launches.
