| struct | PIO48_config_s |
| | 48 Bit pio configuration. This struct is contained within the SeaMAX_PIO_ioctl_s struct. It is used whenever retrieving or setting port direction on a PIO device with 48 bits of I/O. More...

| struct | PIO96_config_s |
| | 96 Bit pio configuration. This struct is contained within the SeaMAX_PIO_ioctl_s struct. It is used whenever retrieving or setting port direction on a PIO device with 96 bits of I/O. More...

| |
| struct | seaio_ioctl_address_s |
| | This struct is used to set the address of a particular device. In this way, it becomes unnecessary to manually turn the screw terminal to configure a particular SeaIO device. It also allows for more devices than the physically selectable 15 addresses. More...

| |
| struct | seaio_ioctl_comms_s |
| | Communication parameters (desired) struct. This struct can be used to set a desired communication configuration. Note that you must first call get params before you attempt to set params, or it will fail. More...
|
| |
| struct | seaio_ioctl_get_params_s |
| | Communication parameters (current) struct. This struct can be used to store the current communication parameters. Note that you will have call get params before you may set a configuration, or it will fail. More...

| struct | seaio_ioctl_ext_config |
| | PIO data/setup struct. This struct can be used to read data from a PIO device, or configure a PIO device. More...
|
| |
| struct | seaio_ioctl_s |
| | The IOCTL struct used in the majority of the IOCTL calls. Every call except the three involving A/D and D/A converters use this struct. This struct is actually the union of several smaller structs, so that it can be used multiple times. More...
