# ACE\_QoS(3)

Wrapper class that holds the sender and receiver flow spec information, which is used by IntServ (RSVP) and DiffServ.

## NAME

ACE\_QoS -  Wrapper class that holds the sender and receiver flow spec information, which is used by IntServ (RSVP) and DiffServ.

## SYNOPSIS

```
#include <ace/OS.h>
class ACE_QoS : public QOS
{
  public:
    ACE_Flow_Spec sending_flowspec (void);
    void sending_flowspec (const ACE_Flow_Spec &fs);
    ACE_Flow_Spec receiving_flowspec (void);
    void receiving_flowspec (const ACE_Flow_Spec &fs);
    iovec provider_specific (void);
    void provider_specific (const iovec &ps);
    class ACE_QoS_Params
    {
      public:

            iovec *caller_data = 0,
            iovec *callee_data = 0,

## Get/set the flow spec for data sending.

```
ACE_Flow_Spec sending_flowspec (void);
```

```
void sending_flowspec (const ACE_Flow_Spec &fs);
```

## Get/set the flow spec for data receiving.

```
ACE_Flow_Spec receiving_flowspec (void);
```

```
void receiving_flowspec (const ACE_Flow_Spec &fs);
```

## Get/set the provider specific information.

```
iovec provider_specific (void);
```

```
void provider_specific (const iovec &ps);
```

## Applications shouldn't use these so they're hidden here.

They're public so that the ACE\_Object\_Manager can be constructed/destructed in main with ACE\_HAS\_NONSTATIC\_OBJECT\_MANAGER.

```
ACE_OS_Object_Manager (void);
```

Constructor.

```
~ACE_OS_Object_Manager (void);
```

Destructor.

## The ACE\_Sched\_Priority type should be used for platform-

independent thread and process priorities, by convention. int should be used for OS-specific priorities.

## Giving unique ACE scoped names for some important

RTSignal-Related constants. Becuase sometimes, different platforms use different names for these constants.
