23bdd0ed36 more work on physics client c-api over shared memory 2015-09-17 09:37:44 -07:00
=
003a42478b another step closer to useable shared memory C API 
(force/torque sensor needs new API)
in a nutshell, users of shared memory physics API should not
directly poke into shared memory, not fill 'SharedMemorCommand'
nor read SharedMemoryStatus directly. The C-API declares 'handles' for those,
to avoid it from happening.

Detach posix shared memory correctly
 2015-09-09 15:13:27 -07:00
Takuya NAKAOKA
4cbd86a058 Detach posix shared memory correctly 
* shmget() fails after shmctl() is called with IPC_RMID. This patch
removes shmget() in releaseSharedMemory so that a client can detach
a shared memory correctly after a server removed it.
* A server should also detach a shared memory.
