API
Table 17. Read configuration (continued)
ld_read_configuration
Parameters
ifc – the interface to address
data – structure that will contain the NAD and all the n PIDs for the frames of the
specified NAD
length – length of data (1+n, NAD+PIDs)
Return
LD_READ_OK
If the service was successful.
LD_LENGTH_TOO_SHORT If the configuration size is greater than the length. It
means that the data area does not contain a valid configuration.

Description
It configures the NAD and the PIDs according to the configuration given by data. It
will not transport anything on the bus. (See [2] section 7.3.1.7)
To be called when it wants to restore a saved configuration or set an initial
configuration (e.g. coded by I/O pins).It shall be called after calling l_ifc_init().
The caller shall set the size of the data area before calling it.
The data contains the NAD and the PIDs and occupies one byte each.
The structure of the data is: NAD and then all PIDs for the frames.
The order of the PIDs is the same as the frame list in the LDF and NCF (See [2]
section 9.2.2.2 and section 8.2.5 respectively).
Parameters
ifc – the interface to address
data – structure containing the NAD and all the n PIDs for the frames of the
specified NAD
length – length of data (1+n, NAD+PIDs)
Return
LD_SET_OK
If the service was successful.
LD_LENGTH_NOT_CORRECT
If the required size of the configuration is not equal to the given length.
LD_DATA_ERROR
The set of configuration could not be made.
