Function pamoja_modbus_raw 

#[unsafe(no_mangle)]
pub unsafe extern "C" fn pamoja_modbus_raw(
    address: u8,
    function: u8,
    data: *const u8,
    data_len: usize,
    out_buffer: *mut *mut PamojaBuffer,
) -> PamojaStatus

Builds a request frame from a raw function code and data.

This is the escape hatch for the function codes the SDK does not name.

Returns

PamojaStatus::Ok on success, with *out_buffer set to a new buffer handle holding the frame, or PamojaStatus::InvalidArgument if the data is longer than a PDU may be.

Safety

data must point to at least data_len readable bytes, or be null when data_len is 0, and out_buffer must point to a writable *mut PamojaBuffer.
