Field Documentation

union { ... } rtio_sqe::@369

arg0

void* rtio_sqe::arg0

Last argument given to callback.

buf

uint8_t* rtio_sqe::buf

Buffer to use.

buf_len

uint32_t rtio_sqe::buf_len

Length of buffer.

callback

rtio_callback_t rtio_sqe::callback

flags

uint16_t rtio_sqe::flags

Op Flags.

i2c_config

uint32_t rtio_sqe::i2c_config

OP_I2C_CONFIGURE.

iodev

const struct rtio_iodev* rtio_sqe::iodev

Device to operation on.

iodev_flags

uint16_t rtio_sqe::iodev_flags

Op iodev flags.

op

uint8_t rtio_sqe::op

Op code.

prio

uint8_t rtio_sqe::prio

Op priority.

rx_buf

uint8_t* rtio_sqe::rx_buf

tiny_buf

uint8_t rtio_sqe::tiny_buf[7]

Tiny buffer.

tiny_buf_len
