Function dds_create_domain 

pub unsafe extern "C" fn dds_create_domain(
    domain: dds_domainid_t,
    config: *const c_char,
) -> dds_entity_t

@brief Creates a domain with a given configuration @ingroup domain @component domain

To explicitly create a domain based on a configuration passed as a string. A domain created in this manner must be explicitly deleted by calling @ref dds_delete on the domain (or on DDS_CYCLONEDDS_HANDLE).

It will not be created if a domain with the given domain id already exists. This could have been created implicitly by a previous call to this function, @ref dds_create_participant or @ref dds_create_domain_with_rawconfig.

The domain configuration is constructed by amending the default configuration with the Domain configuration (fragments) for which the domain id is specifed as “any” and those for which the domain id matches the specified domain id in the order in which they are encountered in the configuration.

Using NULL or “” as config will create a domain with default settings.

@param[in] domain The domain to be created. DDS_DEFAULT_DOMAIN is not allowed. @param[in] config A configuration string containing file names and/or XML fragments representing the configuration.

@returns A valid entity handle or an error code.

@retval DDS_RETCODE_BAD_PARAMETER Illegal value for domain id or the configfile parameter is NULL. @retval DDS_RETCODE_PRECONDITION_NOT_MET The domain already existed and cannot be created again. @retval DDS_RETCODE_ERROR An internal error has occurred.
