Detailed Description

A buffer pool manages memory for a homogeneous set of buffers. Each buffer is the pool start at a 16-byte alignment boundary.

Member Function Documentation

at()

virtual ptr_type uhd::transport::buffer_pool::at ( const size_t  index ) const

pure virtual

Get a pointer to the buffer start at the specified index.

make()

static sptr uhd::transport::buffer_pool::make ( const size_t  num_buffs, const size_t  buff_size, const size_t  alignment = 16  )

static

Make a new buffer pool.

Parameters

num_buffs	the number of buffers to allocate

alignment	the alignment boundary in bytes

Returns

a new buffer pool buff_size X num_buffs

size()

virtual size_t uhd::transport::buffer_pool::size ( void  ) const

pure virtual

Get the number of buffers in this pool.
