NVCVStatus nvcvAllocatorFreeCudaMemory(NVCVAllocatorHandle halloc, void *ptr, int64_t sizeBytes, int32_t alignBytes)

Frees a cuda-accessible memory buffer.

It’s usually used when implementing operators.

Parameters:

• halloc – [in] Handle to the memory allocator object to be used.

  • Must have been created by nvcvAllocatorCreate.

• memType – [in] Type of memory to be freed.

• ptr – [in] Pointer to the memory buffer to be freed. It can be NULL. In this case, no operation is performed.

  • Must have been allocated by nvcvAllocatorAllocCudaMemory.

• sizeBytes, alignBytes – [in] Parameters passed during buffer allocation.

  • Not passing the exact same parameters passed during allocation will lead to undefined behavior.

Return values:

• NVCV_ERROR_INVALID_ARGUMENT – Some parameter is outside its valid range.

• NVCV_SUCCESS – Operation completed successfully.
