/**
* @ingroup libosip2 The GNU oSIP stack
* @defgroup howto_portability How-To handle portability.
* @section howto_portability1 Description.
The libosip2 library also offer high portability through a common API
for conditions variables, fifos, threads, mutex and semaphore: all you
need to write portable applications.
The target and active development platforms are: linux, windows, macosx,
android and iOS. Those platforms are tested every day and you can use
the git repository without fear!
Additionnaly, wince, windows mobile, vxworks, unix, linux on arm -and more-
have been also tested regularly. If you have troubles for some system,
please ask the mailing list (osip-dev@gnu.org)
~~~~~~~{.c}
#include <osip2/osip_mt.h>
#include <osip2/osip_fifo.h>
#include <osip2/osip_condv.h>
#include <osip2/osip_time.h>
~~~~~~~
* @section howto_portability2 Threads
+ Here is code to show how to start a thread:
~~~~~~~{.c}
void *_my_thread (void *arg)
{
struct sometype_t *excontext = (struct sometype_t *) arg;
int i;
while (stopthread == 0) {
do_actions (excontext);
}
osip_thread_exit ();
return NULL;
}
struct osip_thread *thread;
thread = osip_thread_create (20000, _my_thread, argpointer);
~~~~~~~
+ Here is code to show how to terminate a thread:
~~~~~~~{.c}
i = osip_thread_join (thread);
osip_free (thread);
~~~~~~~
* @section howto_portability3 Mutex
+ Here is code to show how to create/lock/unlock/release:
~~~~~~~{.c}
struct osip_mutex *mutex;
mutex = osip_mutex_init ();
osip_mutex_lock (mutex);
do_actions ();
osip_mutex_unlock (mutex);
osip_mutex_destroy (mutex);
~~~~~~~
* @section howto_portability4 Time
libosip2 is also providing a common time API.
This is usefull to implement in various way
a CLOCK_MONOTONIC time and make time adjustement
when a drift is discovered against realtime
clock.
**Note**: It is required to call osip_compensatetime
on Android which goes regularly into deep sleep mode.
When this happens, the MONOTONIC clock is not
increasing. This may also happen for other OS as
well.
~~~~~~~{.c}
int osip_gettimeofday (struct timeval *tp, void *tz);
void osip_compensatetime ();
~~~~~~~
