AvcResponseCode enumeration (avc.h)

The AvcResponseCode enumeration type is used to indicate the type of response received by a subunit driver from its AV/C subunit through AVC_FUNCTION_COMMAND or AVC_FUNCTION_SEND_RESPONSE function codes.

Syntax

typedef enum _tagAvcResponseCode {
  AVC_RESPONSE_NOTIMPL,
  AVC_RESPONSE_ACCEPTED,
  AVC_RESPONSE_REJECTED,
  AVC_RESPONSE_IN_TRANSITION,
  AVC_RESPONSE_STABLE,
  AVC_RESPONSE_IMPLEMENTED,
  AVC_RESPONSE_CHANGED,
  AVC_RESPONSE_INTERIM
} AvcResponseCode;

Constants

AVC_RESPONSE_NOTIMPL Indicates the subunit does not support the specified control command.
AVC_RESPONSE_ACCEPTED Indicates the subunit does implement the specified control command and that subunit state permits execution of the command. Note: Command execution may not have completed by the time the AVC_RESPONSE_ACCEPTED has been returned.
AVC_RESPONSE_REJECTED Specifies a response indicating the command or request was rejected.
AVC_RESPONSE_IN_TRANSITION Specifies a response indicating the command or request was accepted.
AVC_RESPONSE_STABLE Indicates the subunit implements the command. Same meaning as AVC_RESPONSE_IMPLMENTED.
AVC_RESPONSE_IMPLEMENTED Indicates the subunit implements the command. Same meaning as AVC_RESPONSE_STABLE.
AVC_RESPONSE_CHANGED Indicates the subunit state has changed.
AVC_RESPONSE_INTERIM Indicates the subunit is unable to respond with either AVC_RESPONSE_ACCEPTED or AVC_RESPONSE_REJECTED within the 100 millisecond timeframe for responses. The subunit will ultimately return a response frame with either a AVC_RESPONSE_ACCEPTED or AVC_RESPONSE_REJECTED code.
