## NAME

ACE\_Typed\_SV\_Message\_Queue -  Defines the header file for the C++ wrapper for message queues.

## SYNOPSIS

```
#include <ace/Typed_SV_Message_Queue.h>
template<class T>
class ACE_Typed_SV_Message_Queue
{
  public:
        enum{ ACE_CREATE = IPC_CREAT,
        ACE_OPEN = 0,
        ACE_NOWAIT = IPC_NOWAIT };

    ACE_Typed_SV_Message_Queue (void);
    ACE_Typed_SV_Message_Queue (
        key_t external_id,
        int create = ACE_OPEN,
        int perms = ACE_DEFAULT_FILE_PERMS
        );
    int open (
        key_t external_id,
        int create = ACE_OPEN,
        int perms = ACE_DEFAULT_FILE_PERMS
        );
    int close (void);
    int remove (void);
    ~ACE_Typed_SV_Message_Queue (void);
    int send (const ACE_Typed_SV_Message<T> &mb, int mflags = 0);
    int recv (ACE_Typed_SV_Message<T> &mb, int mflags = 0);
    int control (int option, void *arg = 0);
    void dump (void) const;
    ACE_ALLOC_HOOK_DECLARE;
  private:
    ACE_SV_Message_Queue message_queue_;
};
```

## Initialization and termination operations.

    key_t external_id,
    int create = ACE_OPEN,
    int perms = ACE_DEFAULT_FILE_PERMS
    );
```

```
int open (
    key_t external_id,
    int create = ACE_OPEN,
    int perms = ACE_DEFAULT_FILE_PERMS
    );
```

```
int close (void);
```

```
int remove (void);
```

```
~ACE_Typed_SV_Message_Queue (void);
```

## Send and recv methods.

```
int send (const ACE_Typed_SV_Message<T> &mb, int mflags = 0);
```

```
int recv (ACE_Typed_SV_Message<T> &mb, int mflags = 0);
```

```
int control (int option, void *arg = 0);
```
