Function

Allocation of pinned host memory

CUDA function C/C++	#include <cudaVFstd.h> fVector cudaVF_pinnedVector( fVector *h_X, ui size );
CUDA function Pascal/Delphi	uses VecLib; function cudaVF_pinnedVector( var h_X:fVector; size:UIntSize ): fVector;

Description

Pinned host memory is allocated. The device pointer is returned, and the host pointer is stored as h_X. In order to release the memory thus allocated, use cudaV_pinnedFree, cudaV_pinnedFreeAll, or cudaV_pinnedNfree (the latter only in C/C++).
See CudaOptiVec.htm, chapter 3 for a description of the various memory types of cudaOptiVec routines.

Error handling

If there is not enough memory available, or if size is zero, an error message "Not enough memory" is displayed and the program aborted.

Return value

Device pointer to the allocated memory
