The component that will generate a mark event upon processing this buffer.

size of the buffer allocated, in bytes

number of bytes currently in the buffer

buffer specific flags

The index of the input port (if any) using this buffer

start offset of valid data in bytes from the start of the buffer

The index of the output port (if any) using this buffer

size of the structure in bytes

Optional entry that the component and application can update with a tick count when they access the component. This value should be in microseconds. Since this is a value relative to an arbitrary starting point, this value cannot be used to determine absolute time. This is an optional entry and not all components will update it.

Timestamp corresponding to the sample starting at the first logical sample boundary in the buffer. Timestamps of successive samples within the buffer may be inferred by adding the duration of the of the preceding buffer to the timestamp of the preceding buffer.

Pointer to actual block of memory that is acting as the buffer

pointer to any data the input port wants to associate with this buffer

Application specific data associated with the mark sent on a mark event to disambiguate this mark from others.

pointer to any data the output port wants to associate with this buffer

pointer to any data the platform wants to associate with this buffer
