SetNfcEnabled

Takes an input bool, no output.

OutputTestWave

Takes an input bool and a #TestWaveType, no output.

ReadMifare

Takes an input #DeviceHandle, a type-0x6 output buffer containing an array of #MifareReadBlockData, a type-0x5 input buffer containing an array of #MifareReadBlockParameter, no output.

sdknso passes the same user-specified array-count for both buffers.

WriteMifare

Takes an input #DeviceHandle, a type-0x5 input buffer containing an array of #MifareWriteBlockParameter, no output.

SendCommandByPassThrough

Takes an input #DeviceHandle, a nn::TimeSpan, a type-0x6 output buffer, a type-0x5 input buffer, returns an output u32 out_size.

sdknso copies the output u32 into an u64. This is the actual size which was copied into the output buffer.

This allows using a raw NFC command. The input buffer contains the command data (id + params), and the output buffer contains the response.

KeepPassThroughSession

Takes an input #DeviceHandle, no output.

ReleasePassThroughSession

Takes an input #DeviceHandle, no output.

DeviceHandle

This is "nn::nfc::DeviceHandle". This is a 8-byte struct with 4-byte alignment.

TestWaveType

This is u32 enum "nn::nfc::TestWaveType".

MifareReadBlockData

This is "nn::nfc::MifareReadBlockData". This is a 0x18-byte struct.
