rmw_guard_condition_t *rmw_create_guard_condition(rmw_context_t *context)

Create a guard condition and return a handle to that guard condition.

This function can fail, and therefore return NULL, if:

• context is NULL

• context is invalid

• memory allocation fails during guard condition creation

• an unspecified error occurs

The context must be non-null and valid, i.e. it has been initialized by rmw_init() and has not been finalized by rmw_shutdown().
