* Implementation of local continuations based on switch() statment
|

* \author Adam Dunkels <adam@sics.se>
|
||||
*
|
||||
* This implementation of local continuations uses the C switch()
|
||||
* statement to resume execution of a function somewhere inside the
|
||||
* function's body. The implementation is based on the fact that
|
||||
* switch() statements are able to jump directly into the bodies of
|
||||
* control structures such as if() or while() statmenets.
|
||||
*
|
||||
* This implementation borrows heavily from Simon Tatham's coroutines
|
||||
* implementation in C:

/**

|
||||
* @{
|
||||
*
|
||||
* The protosocket library provides an interface to the uIP stack that is
|
||||
* similar to the traditional BSD socket interface. Unlike programs
|
||||
* written for the ordinary uIP event-driven interface, programs
|
||||
* written with the protosocket library are executed in a sequential
|
||||
* fashion and does not have to be implemented as explicit state
|
||||
* machines.
|
||||
*
|
||||
* Protosockets only work with TCP connections.
|
||||
*
|
||||
* The protosocket library uses \ref pt protothreads to provide
|
||||
* sequential control flow. This makes the protosockets lightweight in
|
||||
* terms of memory, but also means that protosockets inherits the
|
||||
* functional limitations of protothreads. Each protosocket lives only
|
||||
* within a single function. Automatic variables (stack variables) are
|
||||
* not retained across a protosocket library function call.
|
||||
*
|
||||
* \note Because the protosocket library uses protothreads, local
|
||||
* variables will not always be saved across a call to a protosocket
|
||||
* library function. It is therefore advised that local variables are
|
||||
* used with extreme care.
|
||||
*
|
||||
* The protosocket library provides functions for sending data without
|
||||
* having to deal with retransmissions and acknowledgements, as well
|
||||
* as functions for reading data without having to deal with data
|
||||
* being split across more than one TCP segment.
|
||||
*
|
||||
* Because each protosocket runs as a protothread, the protosocket has to be
|
||||
* started with a call to PSOCK_BEGIN() at the start of the function
|
||||
* in which the protosocket is used. Similarly, the protosocket protothread can
|
||||
* be terminated by a call to PSOCK_EXIT().
