Mmemonic: rmr_api_static_test.c
Abstract: Specific tests related to the API functions in rmr_nng.c/rmr.c.
This should be included by a driver, but only the main RMr
- driver and there likely not be a specific stand alone driver
+ driver and there will likely not be a specific stand alone driver
for just this small set of tests because of the depth of the
library needed to test at this level.
+ This can be used for both the nng and nanomsg outward facing
+ RMr API functions.
+
The message buffer specific API tests are in a different static
module. API functions tested here are:
