USB-I/O Interface Adapter GPIO-24. Programmer's Reference Manual.
2.1.6. GPIO_CloseAllDevices()
Functions referenced in current section use GPIO_COMMAND and GPIO_EVENT structures.
The declaration of the GPIO_COMMAND structure is:
typedef struct _GPIO_COMMAND
{
unsigned char command[8];
} GPIO_COMMAND, *PGPIO_COMMAND;
Members:
- command
8-byte array filled with a command to be sent to GPIO-24 adapter.
The declaration of the GPIO_EVENT structure is:
typedef struct _GPIO_EVENT
{
unsigned char event[8];
LARGE_INTEGER timestamp;
HGPIO device;
} GPIO_EVENT, *PGPIO_EVENT;
Members:
- event
8-byte array to be filled with an event or response received from GPIO-24 adapter.
- timestamp
Timestamp filled with the RDTSC (Read Time Stamp Counter) high-resolution timer value at the moment the event was received by USB host.
- device
Handle to the device that has generated the event, or HGPIO_DLL_NOTIFICATION constant value if the event was generated internally by the DLL.
