Authors: Adam Dunkels, Leon Woestenberg, Christiaan Simons
lwIP provides two Application Program's Interfaces (APIs) for programs
lwIP provides three Application Program's Interfaces (APIs) for programs
to use for communication with the TCP/IP code:
* low-level "core" / "callback" or "raw" API.
* higher-level "sequential" API.
* BSD-style socket API.
The sequential API provides a way for ordinary, sequential, programs
to use the lwIP stack. It is quite similar to the BSD socket API. The
@@ -14,6 +15,45 @@ paradigm. Since the TCP/IP stack is event based by nature, the TCP/IP
code and the application program must reside in different execution
contexts (threads).
The socket API is a compatibility API for existing applications,
currently it is built on top of the sequential API. It is meant to
provide all functions needed to run socket API applications running
on other platforms (e.g. unix / windows etc.). However, due to limitations
in the specification of this API, there might be incompatibilities
that require small modifications of existing programs.
** Threading
lwIP started targeting single-threaded environments. When adding multi-
threading support, instead of making the core thread-safe, another
approach was chosen: there is one main thread running the lwIP core
(also known as the "tcpip_thread"). The raw API may only be used from
this thread! Application threads using the sequential- or socket API
communicate with this main thread through message passing.
As such, the list of functions that may be called from
other threads or an ISR is very limited! Only functions
from these API header files are thread-safe:
- api.h
- netbuf.h
- netdb.h
- netifapi.h
- sockets.h
- sys.h
Additionaly, memory (de-)allocation functions may be
called from multiple threads (not ISR!) with NO_SYS=0
since they are protected by SYS_LIGHTWEIGHT_PROT and/or
semaphores.
Only since 1.3.0, if SYS_LIGHTWEIGHT_PROT is set to 1
and LWIP_ALLOW_MEM_FREE_FROM_OTHER_CONTEXT is set to 1,
pbuf_free() may also be called from another thread or
an ISR (since only then, mem_free - for PBUF_RAM - may
be called from an ISR: otherwise, the HEAP is only
protected by semaphores).
