Member Function Documentation

cast()

template<class T >

UHD_INLINE T uhd::transport::managed_buffer::cast ( void  ) const

inline

Get a pointer to the underlying buffer.

Returns

a pointer into memory

commit()

UHD_INLINE void uhd::transport::managed_buffer::commit ( size_t  num_bytes )

inline

Use commit() to re-write the length (for use with send buffers).

Parameters

num_bytes

the number of bytes written into the buffer

make()

template<typename T >

UHD_INLINE boost::intrusive_ptr<T> uhd::transport::managed_buffer::make ( T *  p, void *  buffer, size_t  length  )

inline

Create smart pointer to a reusable managed buffer.

ref_count()

int uhd::transport::managed_buffer::ref_count ( )

inline

release()

virtual void uhd::transport::managed_buffer::release ( void  )

pure virtual

Signal to the transport that we are done with the buffer. This should be called to release the buffer to the transport object. After calling, the referenced memory should be considered invalid.

size()

UHD_INLINE size_t uhd::transport::managed_buffer::size ( void  ) const

inline

Get the size of the underlying buffer.

Returns

the number of bytes
