+ Mmemonic: rmr_si_api_static_test.c
+ Abstract: Specific tests related to the API functions in rmr_si.c.
+ This should be included by a driver which invokes the 'main'
+ test function here: rmr_api_test.
+
+ This test set applies only to the outward facting API functions
+ in the rmr_si.c module (mostly because the context for SI is
+ different).
+
+ The message buffer specific API tests are in a different static
+ module. API functions tested here are:
+ rmr_close
+ rmr_get_rcvfd
+ rmr_ready
+ rmr_init
+ rmr_set_rtimeout
+ rmr_set_stimeout
+ rmr_rcv_specific
+ rmr_torcv_msg
+ rmr_rcv_msg
+ rmr_call
+ rmr_rts_msg
+ rmr_send_msg
+ rmr_mtosend_msg
+ rmr_free_msg
