This structure represents an SRP client service.

#include < include/openthread/srp_client.h >

Public Attributes

const char * mName
The service labels (e.g., "_mt._udp", not the full domain name).
const char * mInstanceName
The service instance name label (not the full name).
const char *const * mSubTypeLabels
Array of sub-type labels (must end with NULL or can be NULL ).
const otDnsTxtEntry * mTxtEntries
Array of TXT entries ( mNumTxtEntries gives num of entries).
uint16_t mPort
The service port number.
uint16_t mPriority
The service priority.
uint16_t mWeight
The service weight.
uint8_t mNumTxtEntries
Number of entries in the mTxtEntries array.
otSrpClientItemState mState
Service state (managed by OT core).
uint32_t mData
Internal data (used by OT core).
struct otSrpClientService * mNext
Pointer to next entry in a linked-list (managed by OT core).
uint32_t mLease
Desired lease interval in sec - zero to use default.
uint32_t mKeyLease
Desired key lease interval in sec - zero to use default.

This structure represents an SRP client service.

The values in this structure, including the string buffers for the names and the TXT record entries, MUST persist and stay constant after an instance of this structure is passed to OpenThread from otSrpClientAddService() or otSrpClientRemoveService() .

The mState , mData , mNext fields are used/managed by OT core only. Their value is ignored when an instance of otSrpClientService is passed in otSrpClientAddService() or otSrpClientRemoveService() or other functions. The caller does not need to set these fields.

The mLease and mKeyLease fields specify the desired lease and key lease intervals for this service. Zero value indicates that the interval is unspecified and then the default lease or key lease intervals from otSrpClientGetLeaseInterval() and otSrpClientGetKeyLeaseInterval() are used for this service. If the key lease interval (whether set explicitly or determined from the default) is shorter than the lease interval for a service, SRP client will re-use the lease interval value for key lease interval as well. For example, if in service mLease is explicitly set to 2 days and mKeyLease is set to zero and default key lease is set to 1 day, then when registering this service, the requested key lease for this service is also set to 2 days.
