MfuncBufAncestorId

Only child buffers have an ancestor buffer. The ancestor buffer is the buffer from which the specified buffer (BufferInfoHandle) ultimately originated. It is the root buffer; it does not have a parent buffer (it is not a child buffer of another buffer).

Note that this function reference has not been updated for a MIL system added during a MIL update. Refer to the MIL system's release note to see if there is complementary information.

Parameters

This function is not supported on the selected boards.

Parameter

BufferInfoHandle

Specifies the handle of the MIL buffer. The buffer handle must be obtained using MfuncInquire() with M_BUFFER_INFO.

Return value

The returned value is the MIL identifier of the specified MIL buffer's ancestor buffer.

Remark

This function is equivalent to using MbufInquire() with M_ANCESTOR_ID, but provides no parameter checking or error reporting.
