uint64 nvbio::DeviceVectorArray< T >::resize ( const uint32  size, const uint32  arena, const bool  do_alloc = true  )

inline

resize the arena

Parameters

size	size of the array (i.e. number of vectors)
arena	size of the memory arena
do_alloc	a flag to indicate whether to really perform allocations; if false, the function will just return the amount of memory needed

Returns

amount of memory allocated/needed
