Expand description
DDS 2.2.3.19 RESOURCE_LIMITS DDS Spec v1.4 p.147 “struct ResourceLimitsQosPolicy” defines the fields as “long”. The “long” type of OMG IDL is defined to have 32-bit (signed, 2’s complement) range in the OMG IDL spec v4.2, Table 7-13: Integer Types.
But it does not make sense to have negative limits, so these should be unsigned.
Negative values are needed, because DDS spec defines the special value const long LENGTH_UNLIMITED = -1;
