Function pamoja_i2c_bus_write_read 

#[unsafe(no_mangle)]
pub unsafe extern "C" fn pamoja_i2c_bus_write_read(
    bus: *const PamojaI2cBus,
    address: u8,
    bytes: *const u8,
    len: usize,
    out: *mut u8,
    out_len: usize,
) -> PamojaStatus

Writes bytes to a part and reads its reply in one transaction, with a repeated start between them, which is how a register is read.

Arguments

• bus - the bus.
• address - the part’s 7-bit address.
• bytes - what to write first, usually the register address.
• len - how many bytes to write.
• out - receives the reply.
• out_len - how many bytes to read.

Returns

As pamoja_i2c_bus_write.

Safety

bus must be a live handle or null, bytes must point to len readable bytes, and out to out_len writable bytes.
