egd_close - close a device
int egd_close(struct eegdev* dev);
egd_close() frees all resources associated to the device referenced by dev and closes it. It stops also implicitely any running acquisition.
After a successful call to egd_close(), the reference dev cannot be used any longer.
The function returns 0 in case of succes. Otherwise, -1 is returned and errno is set accordingly.
egd_close() will fail if:
- dev is NULL.
