int init(int version, const char * fom_path, const char * federate_name, const char * federation_execution_name)
Initializes the HLA Client using the given parameters.Arguments
- int version - Callback type. One of the following values: RTI13, RTI1516, or RTI1516E.
- const char * fom_path - path to FOM file (.fed or .xml, depends on version)
- const char * federate_name - name of the current instance

1 if the HLA Client was initialized successfully; otherwise, 0.void setTimeRegulation(bool start_constrained, bool start_regulating)
Sets time management mode for the federate. In general, a federate may be "regulating," "constrained," "regulating and constrained," or "neither regulating nor constrained.Arguments
