Macro Definition Documentation

#define SOAPY_SDR_END_ABRUPT   (1 << 3)

Indicates that stream terminated prematurely. This is the flag version of an overflow error that indicates an overflow with the end samples.

#define SOAPY_SDR_END_BURST   (1 << 1)

Indicate end of burst for transmit or receive. For write, end of burst if set by the caller. For read, end of burst is set by the driver.

#define SOAPY_SDR_HAS_TIME   (1 << 2)

Indicates that the time stamp is valid. For write, the caller must set has time when timeNs is provided. For read, the driver sets has time when timeNs is provided.

#define SOAPY_SDR_MORE_FRAGMENTS   (1 << 5)

Indicate that this read call and the next results in a fragment. Used when the implementation has an underlying packet interface. The caller can use this indicator and the SOAPY_SDR_ONE_PACKET flag on subsequent read stream calls to re-align with packet boundaries.

#define SOAPY_SDR_ONE_PACKET   (1 << 4)

Indicates transmit or receive only a single packet. Applicable when the driver fragments samples into packets. For write, the user sets this flag to only send a single packet. For read, the user sets this flag to only receive a single packet.

#define SOAPY_SDR_RX   1

Constant to represent the receive direction

#define SOAPY_SDR_TX   0

Constant to represent the transmit direction
