## Detailed Description

template<typename T, class SVMTrait>
class cl::SVMAllocator< T, SVMTrait >

STL-like allocator class for managing SVM objects provided for convenience.

Note that while this behaves like an allocator for the purposes of constructing vectors and similar objects, care must be taken when using with smart pointers. The allocator should not be used to construct a unique_ptr if we are using coarse-grained SVM mode because the coarse-grained management behaviour would behave incorrectly with respect to reference counting.

Instead the allocator embeds a Deleter which may be used with unique_ptr and is used with the allocate_shared and allocate_ptr supplied operations.

pointer cl::SVMAllocator< T, SVMTrait >::allocate | ( | size_type | size,
|  | typename cl::SVMAllocator< void, SVMTrait >::const_pointer | = `0`

If the allocator is coarse-grained, this will take ownership to allow containers to correctly construct data in place.
