Receiver side for the record oriented C++ wrapper for UNIX FIFOs.

## NAME

ACE\_FIFO\_Recv\_Msg -  Receiver side for the record oriented C++ wrapper for UNIX FIFOs.

## SYNOPSIS

```
#include <ace/FIFO_Recv_Msg.h>
class ACE_FIFO_Recv_Msg : public ACE_FIFO_Recv
{
  public:
    ACE_FIFO_Recv_Msg (void);
    ACE_FIFO_Recv_Msg (
        const ASYS_TCHAR *rendezvous,
        int flags = O_CREAT | O_RDONLY,
        int perms = ACE_DEFAULT_FILE_PERMS,
        int persistent = 1,
        LPSECURITY_ATTRIBUTES sa = 0
        );
    int open (
        const ASYS_TCHAR *rendezvous,
        int flags = O_CREAT | O_RDONLY,
        int perms = ACE_DEFAULT_FILE_PERMS,
        int persistent = 1,
        LPSECURITY_ATTRIBUTES sa = 0
        );
    ssize_t recv (ACE_Str_Buf &msg);
    ssize_t recv (void *buf, size_t len);
    ssize_t recv (ACE_Str_Buf *data, ACE_Str_Buf *cntl, int *flags);
    ssize_t recv (
        int *band,
        ACE_Str_Buf *data,
        ACE_Str_Buf *cntl,
        int *flags
        );
    void dump (void) const;
    ACE_ALLOC_HOOK_DECLARE;
};
```

## Initialization methods.

```
ACE_FIFO_Recv_Msg (void);
```

Default constructor.

```
ACE_FIFO_Recv_Msg (
    const ASYS_TCHAR *rendezvous,
    int flags = O_CREAT | O_RDONLY,
    int perms = ACE_DEFAULT_FILE_PERMS,
    int persistent = 1,
    LPSECURITY_ATTRIBUTES sa = 0
    );
```

Open up a record-oriented named pipe for reading.

```
int open (
    const ASYS_TCHAR *rendezvous,
    int flags = O_CREAT | O_RDONLY,
    int perms = ACE_DEFAULT_FILE_PERMS,
    int persistent = 1,
    LPSECURITY_ATTRIBUTES sa = 0
    );
```

Open up a record-oriented named pipe for reading.

```
ssize_t recv (ACE_Str_Buf &msg);
```

Recv msg as an ACE\_Str\_Buf.

```
ssize_t recv (void *buf, size_t len);
```

Recv msg as a buffer.

```
ssize_t recv (ACE_Str_Buf *data, ACE_Str_Buf *cntl, int *flags);
```

Recv data and cntl message via Stream pipes.

```
ssize_t recv (
    int *band,
    ACE_Str_Buf *data,
    ACE_Str_Buf *cntl,
    int *flags
    );
```

Recv data and cntl message via Stream pipes in "band" mode.

```
void dump (void) const;
```
