5Description:
6		The cdev interface to drivers for Fieldbus Device Memory
7			(aka. Process Memory).
8
9		The following file operations are supported:
10
11		open(2)
12		Create an I/O context associated with the file descriptor.
13
14		read(2)
15		Read from Process Memory's "read area".
16		Clears POLLERR | POLLPRI from the file descriptor.
17
18		write(2)
19		Write to Process Memory's "write area".
20
21		poll(2), select(2), epoll_wait(2) etc.
22		When a "Process Memory Read Area Changed" event occurs,
23		POLLERR | POLLPRI will be set on the file descriptor.
24		Note that POLLIN | POLLOUT events are always set, because the
25		process memory area is always readable and writable.
26
27		close(2)
28		Free up the I/O context that was associated
29		with the file descriptor.
