Enumeration Type Documentation

◆ dwSignalE2EStatus

enum dwSignalE2EStatus

End-2-End related status of the signal.

Enumerator
DW_SIGNAL_E2E_NO_ERROR	No E2E error.
DW_SIGNAL_E2E_SEQ_ERROR	E2E Sequence error. Signal arrived out of sequence or having skipped values
DW_SIGNAL_E2E_HASH_ERROR	Hash error. Signal did not verify against hash properly.
DW_SIGNAL_E2E_NO_INFORMATION	No E2E information.
DW_SIGNAL_E2E_MAX_ENUM_VALUE	Signal enum max value.

Definition at line 96 of file SignalStatus.h.

◆ dwSignalStatus

enum dwSignalStatus

Overall status of the signal.

Enumerator
DW_SIGNAL_STATUS_INIT	Initial value. Means that the signal has never had an assigned value.
DW_SIGNAL_STATUS_LAST_VALID	Signal contains the last valid value that was set.
DW_SIGNAL_STATUS_ERROR	Signal value is in error.
DW_SIGNAL_STATUS_OUT_OF_BOUNDS_ERROR	Signal value is outside acceptable bounds.
DW_SIGNAL_STATUS_MAX_ENUM_VALUE	Signal enum max value.

Definition at line 62 of file SignalStatus.h.

◆ dwSignalTimeoutStatus

enum dwSignalTimeoutStatus

Timeout related status of the signal.

Enumerator
DW_SIGNAL_TIMEOUT_NEVER_RECEIVED	This signal has never been received.
DW_SIGNAL_TIMEOUT_NONE	No timeout error.
DW_SIGNAL_TIMEOUT_OVERDUE	Signal is overdue.
DW_SIGNAL_TIMEOUT_NO_INFORMATION	No timeout information.
DW_SIGNAL_TIMEOUT_DELAYED	Signal received but not for more than twice the specified cycle.
DW_SIGNAL_TIMEOUT_MAX_ENUM_VALUE	Signal enum max value.

Definition at line 78 of file SignalStatus.h.

Function Documentation

◆ dwSignal_decodeSignalValidity()

DW_API_PUBLIC dwStatus dwSignal_decodeSignalValidity	(	dwSignalStatus *	status,
		dwSignalTimeoutStatus *	timeoutStatus,
		dwSignalE2EStatus *	e2eStatus,
		dwSignalValidity const	validity
	)

Decode dwSignal*Status values from a dwSignalValidity value.

Parameters

[out]	status	Signal status after decoding
[out]	timeoutStatus	Signal timeout status after decoding
[out]	e2eStatus	Signal E2E status after decoding
[in]	validity	Encoded signal validity data to decode

Returns: DW_SUCCESS
DW_INVALID_ARGUMENT - If validity contains invalid data or if one of the statuses is null

◆ dwSignal_encodeSignalValidity()

DW_API_PUBLIC dwStatus dwSignal_encodeSignalValidity	(	dwSignalValidity *	validity,
		dwSignalStatus const	status,
		dwSignalTimeoutStatus const	timeoutStatus,
		dwSignalE2EStatus const	e2eStatus
	)

Encode dwSignal*Status values into a dwSignalValidity value.
