Detailed Description

This buffer can be used by one read and one write thread at any one time without the risk of data corruption. If you intend to call the Reset() method, please use Locks. All other operations are thread-safe.

Member Function Documentation

Create()

bool AERingBuffer::Create ( int  size, unsigned int  planes = 1  )

inline

Allocates space for buffer, and sets it's contents to 0.

Returns

true on success, false otherwise

Dump()

void AERingBuffer::Dump ( )

inline

Dumps the buffer.

GetMaxSize()

unsigned int AERingBuffer::GetMaxSize ( )

inline

Returns the buffer size.

GetReadSize()

unsigned int AERingBuffer::GetReadSize ( )

inline

Returns available space for reading from buffer. Attempt to read more bytes than available results in AE_RING_BUFFER_EMPTY.

GetWriteSize()

unsigned int AERingBuffer::GetWriteSize ( )

inline

Returns available space for writing to buffer. Attempt to write more bytes than available results in AE_RING_BUFFER_FULL.

NumPlanes()

unsigned int AERingBuffer::NumPlanes ( ) const

inline

Returns the number of planes

Read()

int AERingBuffer::Read ( unsigned char *  dest, unsigned int  size, unsigned int  plane = 0  )

inline

Reads data from buffer. Attempt to read more bytes than available results in RING_BUFFER_NOTAVAILABLE. Reading from empty buffer returns AE_RING_BUFFER_EMPTY

Returns

AE_RING_BUFFER_OK on success, otherwise an error code

Reset()

void AERingBuffer::Reset ( )

inline

Fills the buffer with zeros and resets the pointers. This method is not thread-safe, so before using this method please acquire a Lock()

Write()

int AERingBuffer::Write ( unsigned char *  src, unsigned int  size, unsigned int  plane = 0  )

inline

Writes data to buffer. Attempt to write more bytes than available results in AE_RING_BUFFER_FULL.

Returns

AE_RING_BUFFER_OK on success, otherwise an error code
