Field Documentation

◆ actual_count

unsigned int actual_count

This output parameter is updated to reflect the actual number of contiguous samples that have been populated in an RX buffer during a bladerf_sync_rx() call.

This will not be equal to the requested count in the event of a discontinuity (i.e., when the status field has the BLADERF_META_STATUS_OVERRUN flag set). When an overrun occurs, it is important not to read past the number of samples specified by this value, as the remaining contents of the buffer are undefined.

Note: This parameter is not currently used by bladerf_sync_tx().

◆ flags

uint32_t flags

Input bit field to control the behavior of the call that the metadata structure is passed to. API calls read this field from the provided data structure, and do not modify it.

Valid flags include BLADERF_META_FLAG_TX_BURST_START, BLADERF_META_FLAG_TX_BURST_END, BLADERF_META_FLAG_TX_NOW, BLADERF_META_FLAG_TX_UPDATE_TIMESTAMP, and BLADERF_META_FLAG_RX_NOW
