# ACE\_Streambuf\_T(3)

## NAME

ACE\_Streambuf\_T

## SYNOPSIS

```
#include <ace/IOStream_T.h>
template<class STREAM>
class ACE_Streambuf_T : public ACE_Streambuf
{
  public:
    ACE_Streambuf_T (
        STREAM *peer,
        u_int streambuf_size = ACE_STREAMBUF_SIZE,
        int io_mode = ios::in | ios::out
        );
    virtual ssize_t send (char *buf, ssize_t len);
    virtual ssize_t recv (
        char *buf,
        ssize_t len,
        ACE_Time_Value *tv = NULL
        );
    virtual ssize_t recv (
        char *buf,
        ssize_t len,
        int flags,
        ACE_Time_Value * tv = NULL
        );
    virtual ssize_t recv_n (
        char *buf,
        ssize_t len,
        int flags = 0,
        ACE_Time_Value *tv = NULL
        );
  protected:
    virtual ACE_HANDLE get_handle (void);
    STREAM *peer_;
};
```

## PUBLIC MEMBERS

```
ACE_Streambuf_T (
    STREAM *peer,
    u_int streambuf_size = ACE_STREAMBUF_SIZE,
    int io_mode = ios::in | ios::out
    );
```

We will be given a STREAM by the iostream object which creates us.  See the ACE\_IOStream template for how that works.  Like other streambuf objects, we can be input-only, output-only or both.

```
virtual ssize_t send (char *buf, ssize_t len);
```

```
virtual ssize_t recv (
    char *buf,
    ssize_t len,
    ACE_Time_Value *tv = NULL
    );
```

```
virtual ssize_t recv (
    char *buf,
    ssize_t len,
    int flags,
    ACE_Time_Value * tv = NULL
    );
```

```
virtual ssize_t recv_n (
    char *buf,
    ssize_t len,
    int flags = 0,
    ACE_Time_Value *tv = NULL
    );
```

## PROTECTED MEMBERS

```
virtual ACE_HANDLE get_handle (void);
```

```
STREAM *peer_;
```

This will be our ACE\_SOCK\_Stream or similar object.
