Function pamoja_modbus_read_holding_registers 

#[unsafe(no_mangle)]
pub unsafe extern "C" fn pamoja_modbus_read_holding_registers(
    address: u8,
    start: u16,
    count: u16,
    out_buffer: *mut *mut PamojaBuffer,
) -> PamojaStatus

Builds a read-holding-registers request frame (function 0x03).

Returns

PamojaStatus::Ok on success, with *out_buffer set to a new buffer handle holding the frame.

Safety

out_buffer must point to a writable *mut PamojaBuffer.
