* Name: sixlowpan_initialize
|
|
*
|
|
* Description:
|
|
* sixlowpan_initialize() is called during OS initialization at power-up
|
|
* reset. It is called from the common net_setup() function.
|
|
* sixlowpan_initialize() configures 6loWPAN networking data structures.
|
|
* It is called prior to platform-specific driver initialization so that
|
|
* the 6loWPAN networking subsystem is prepared to deal with network
|
|
* driver initialization actions.
|
|
*
|
|
* Input Parameters:
|
|
* None
|
|
*
|
|
* Returned Value:

* Function: psock_6lowpan_tcp_send

|
*
|
|
* Description:
|
|
* psock_6lowpan_tcp_send() call may be used only when the TCP socket is in a
|
|
* connected state (so that the intended recipient is known).
|
|
*
|
|
* Parameters:
|
|
* psock - An instance of the internal socket structure.
|
|
* buf - Data to send
|
|
* len - Length of data to send
|
|
*
|
|
* Returned Value:
|
|
* On success, returns the number of characters sent. On error,
|
|
* -1 is returned, and errno is set appropriately. Returned error numbers
|
|
* must be consistent with definition of errors reported by send() or
|
|
* sendto().
|
|
*
|
|
* Assumptions:
|
|
* Called with the network locked.
