/// This operation safely detaches the application from all domains it is currently

/// <remarks>
/// @note This is a proprietary OpenSplice extension.
///
/// This operation safely detaches the application from all domains it is currently
/// participating in. When this operation has been performed successfully,
/// the application is no longer connected to any Domain.
/// - For Federated domains finishing this operation successfully means that all shared
/// memory segments have been safely un-mapped from the application process.
/// - For SingleProcess mode domains this means all services for all domains have been
/// stopped. This allows graceful termination of the OSPL services that run as threads
/// within the application. Graceful termination of services in this mode would for
/// instance allow durability flushing of persistent data and networking termination
/// announcement over the network.
///
/// When this call returns further access to all domains will be denied and it will
/// not be possible for the application to open or re-open any DDS domain.
///
/// The behavior of the DetachAllDomains operation is determined by the blockOperations
/// and deleteEntities parameters:<br>
/// - blockOperations:
/// This parameter specifies if the application wants any DDS operation to be blocked
/// or not while detaching. When true, any DDS operation called during this operation
/// will be blocked and remain blocked forever (so also after the detach operation has
/// completed and returns to the caller). When false, any DDS operation called during
/// this operation may return AlreadyDeleted. Please note that a listener
/// callback is not considered an operation in progress. Of course, if a DDS operation
/// is called from within the listener callback, that operation will be blocked
/// during the detaching if this attribute is set to true.
/// - deleteEntities:
/// This parameter specifies if the application wants the DDS entities created by
/// the application to be deleted (synchronously) while detaching from the domain or
/// not. If true, all application entities are guaranteed to be deleted when the call
/// returns. If false, application entities will not explicitly be deleted by this
/// operation. In case of federated mode, the splice-daemon will delete them
/// asynchronously after this operation has returned. In case of SingleProcess mode
/// this attribute is ignored and clean up will always be performed, as this cannot
/// be delegated to a different process.
///
/// @note In federated mode when the DetachAllDomains operation is called with
/// blockOperations is false and deleteEntities is false then the DDS operations
/// which are in progress and which are waiting for some condition to become true
/// or waiting for an event to occur while the detach operation is performed may be
/// blocked.
/// </remarks>
/// @param blockOperations
/// Indicates whether the application wants any operations that are called while
/// detaching to be blocked or not.
/// @param deleteEntities
/// Indicates whether the application DDS entities in the 'connected' domains must
/// be deleted synchronously during detaching.
