r0ab65474 rdf49c60 1 USING RPC/XDR ON RTEMS 2 ====================== 3 For the most part, programmers using RPC/XDR routines on RTEMS 4 can proceed as if they were to be using a POSIX/UNIX system. 5 The only significant changes are those to start the portmapper 6 and to allow use of RPC/XDR by multiple threads. 7 8 Starting the portmapper 9 ======================= 10 The SUN portmapper program has been modified to run as an RTEMS 11 task. Applications which need the portmapper can start this 12 task by calling: 13 int rtems_rpc_start_portmapper (int priority); 14 The return value is an RTEMS status code. 15 16 Multi-threaded operation 17 ======================== 18 The RPC/XDR package has been modified to allow for multiple RTEMS 19 tasks to use RPC/XDR routines. If more than one task is to call 20 an RPC/XDR routine, the additional tasks must call: 21 int rtems_rpc_task_init(void); 22 before calling any RPC/XDR routines. For example, the portmapper 23 calls this routine since the portmapper uses RPC/XDR routines in 24 a separate thread. 25 The return value is an RTEMS status code. 26 27 28 Porting Notes 29 ============= 30 Most of the FreeBSD rpc library ports to RTEMS with little 31 or no modification beyond that required to provide for operation 32 in a multitasking environment. Multitasking operation was 33 provided by moving all `static persistence' variables into 34 a single structure and using an RTEMS task variable to point 35 to that structure. 36 37 Some of the library, however, has not made it into the RTEMS 38 implementation. FreeBSD source files which have been left out include: 39 - Files which provide RPC to the AF_UNIX address family: 40 clnt_unix.c 41 svc_unix.c 42 An `ifndef __rtems__' was added to clnt_generic.c because clnt_unix.c 43 was omitted. 44 - Files which need NIS: 45 auth_time.c 46 - Files which provide DES authentication: 47 auth_des.c 48 authdes_prot.c 49 crypt_client.c 50 des_crypt.c 51 des_soft.c 52 getpublickey.c 53 key_call.c 54 key_prot_xdr.c 55 svc_auth_des.c 56 57 The FreeBSD xdr source compiles and runs on RTEMS without modification. 58 59 The original source was obtained from: 60 ftp://ftp.FreeBSD.org/pub/FreeBSD/ 61 branches/4.0-stable/src/lib/libc/rpc 62 branches/4.0-stable/src/lib/libc/xdr 63 branches/4.0-stable/src/include/rpc 64 branches/4.0-stable/src/include/rpcsvc
