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

  • Must have been created by nvcvAllocatorCreate.

  • Cannot be NULL.

• sizeBytes – [in] How many bytes to allocate.

  • Must be >= 0.

  • Must be an integral multiple of alignBytes.

• alignBytes – [in] Address alignment in bytes. The returned address will be multiple of this value.

  • Must a power of 2.

Return values:

• NVCV_ERROR_INVALID_ARGUMENT – Some parameter is outside its valid range.

• NVCV_ERROR_OUT_OF_MEMORY – Not enough free memory.
