I use objects of type:

typedef struct object {

=A0 RT_MUTEX *rt_lock;

=A0 ..

} Object;

int err =3D rt_mutex_create (ob->rt_lock, NULL);

printf ("[alloc.c]: rt_mutex_create err: %d; #%d \n", err, __LINE__);

err =3D rt_mutex_acquire (ob->rt_lock, TM_INFINITE);

printf ("[lock.c]: rt_mutex_acquire, err: %d; #%d \n", err, __LINE__);

On creation, rt_mutex_create returns 0 (as expected).

On acquiring, rt_mutex_acquire returns -3,

but this return value is not included among the possible return values in the documentation of Mutex services.

Could you please explain what this return value -3 means?

Best regards

This means that for some reason, the internal handle copied by rt_mutex_create() to ob->rt_lock could not be found back in the system registry when calling rt_mutex_acquire(). Any chance ob->rt_lock may have been overwritten, or this mutex deleted by another thread in the meantime? In userland, RT_MUTEX is a structure containing an opaque long integer value. Maybe you could check that value (printf("%ld", ob->rt_lock.opaque)) right after rt_mutex_create() returns, and just before rt_mutex_acquire() is invoked. > but this return value is not included among the possible return values > in the documentation of Mutex services. >=20 > =20 >=20 > Could you please explain what this return value -3 means? >=20 > =20 >=20 > Best regards >=20 > Hans So =20 >=20 > =20 >=20 > =20 >=20 >=20 > _______________________________________________ > Xenomai-help mailing list > Xenomai-help@domain.hid > https://mail.gna.org/listinfo/xenomai-help --=20 Philippe.
