Macro for creating and initializing an NFC NDEF message descriptor.

This macro creates and initializes an instance of type nfc_ndef_msg_desc and an array of pointers to record descriptors (nfc_ndef_record_desc) used by the message.

Use the macro NFC_NDEF_MSG to access the NDEF message descriptor instance.

Note
The message descriptor is declared as automatic variable, which implies that the NDEF message encoding must be done in the same variable scope.
Parameters

max_record_cntMaximal count of records in the message.
