Function esp_idf_sys::i2c_slave_write_buffer

pub unsafe extern "C" fn i2c_slave_write_buffer(
    i2c_num: i2c_port_t, 
    data: *mut u8, 
    size: c_int, 
    ticks_to_wait: TickType_t
) -> c_int

@brief I2C slave write data to internal ringbuffer, when tx fifo empty, isr will fill the hardware fifo from the internal ringbuffer @note Only call this function in I2C slave mode

@param i2c_num I2C port number @param data data pointer to write into internal buffer @param size data size @param ticks_to_wait Maximum waiting ticks

@return - ESP_FAIL(-1) Parameter error - Others(>=0) The number of data bytes that pushed to the I2C slave buffer.
