The return value is zero for success, else a negative errno. It should
be checked, since the get/set calls don't have error returns and since
misconfiguration is possible. (These calls could sleep.)
+For output GPIOs, the value provided becomes the initial output value.
+This helps avoid signal glitching during system startup.
+
Setting the direction can fail if the GPIO number is invalid, or when
that particular GPIO can't be used in that mode. It's generally a bad
idea to rely on boot firmware to have set the direction correctly, since

-/* SECURE SOCKET IMPLEMENTATION
- *
- * TRANSMIT:
- *
- * When the user sends a packet via send() system call
- * the wanpipe_sendmsg() function is executed.
- *
- * Each packet is enqueud into sk->sk_write_queue transmit
- * queue. When the packet is enqueued, a delayed transmit
- * timer is triggerd which acts as a Bottom Half hander.
- *
- * wanpipe_delay_transmit() function (BH), dequeues packets
- * from the sk->sk_write_queue transmit queue and sends it
- * to the deriver via dev->hard_start_xmit(skb, dev) function.
- * Note, this function is actual a function pointer of if_send()
- * routine in the wanpipe driver.
- *
- * X25API GUARANTEED DELIVERY:
- *
- * In order to provide 100% guaranteed packet delivery,
- * an atomic 'packet_sent' counter is implemented. Counter
- * is incremented for each packet enqueued
- * into sk->sk_write_queue. Counter is decremented each
- * time wanpipe_delayed_transmit() function successfuly
- * passes the packet to the driver. Before each send(), a poll
- * routine checks the sock resources The maximum value of
- * packet sent counter is 1, thus if one packet is queued, the
- * application will block until that packet is passed to the
- * driver.
- *
- * RECEIVE:
- *
- * Wanpipe device drivers call the socket bottom half
- * function, wanpipe_rcv() to queue the incoming packets
- * into an AF_WANPIPE socket queue. Based on wanpipe_rcv()
- * return code, the driver knows whether the packet was
- * successfully queued. If the socket queue is full,
- * protocol flow control is used by the driver, if any,
- * to slow down the traffic until the sock queue is free.
- *
- * Every time a packet arrives into a socket queue the
- * socket wakes up processes which are waiting to receive
- * data.
- *
- * If the socket queue is full, the driver sets a block
- * bit which signals the socket to kick the wanpipe driver
- * bottom half hander when the socket queue is partialy
- * empty. wanpipe_recvmsg() function performs this action.
- *
- * In case of x25api, packets will never be dropped, since
- * flow control is available.
- *
- * In case of streaming protocols like CHDLC, packets will
- * be dropped but the statistics will be generated.

-/* The code below is used to test memory leaks. It prints out
