# ACE\_POSIX\_AIOCB\_Asynch\_Transmit\_File(3)

## NAME

ACE\_POSIX\_AIOCB\_Asynch\_Transmit\_File

## SYNOPSIS

```
class ACE_POSIX_AIOCB_Asynch_Transmit_File :
  public virtual ACE_Asynch_Transmit_File_Impl,
  public ACE_POSIX_AIOCB_Asynch_Operation
{
  public:
    ACE_POSIX_AIOCB_Asynch_Transmit_File (
        ACE_POSIX_AIOCB_Proactor *posix_aiocb_proactor
        );
    int transmit_file (
        ACE_HANDLE file,
        ACE_Asynch_Transmit_File::Header_And_Trailer *header_and_trailer,
        u_long bytes_to_write,
        u_long offset,
        u_long offset_high,
        u_long bytes_per_send,
        u_long flags,
        const void *act,
        int priority,
        int signal_number = 0
        );
    virtual ~ACE_POSIX_AIOCB_Asynch_Transmit_File (void);
    int open (
        ACE_Handler &handler,
        ACE_HANDLE handle,
        const void *completion_key,
        ACE_Proactor *proactor = 0
        );
    int cancel (void);
    ACE_Proactor* proactor (void) const;
};
```

## DESCRIPTION

The implementation classes for POSIX implementation of Asynch Operations are defined here in this file.

## Methods belong to ACE\_POSIX\_Asynch\_Operation base class. These

methods are defined here to avoid dominace warnings. They route  the call to the ACE\_POSIX\_Asynch\_Operation base class.

```
int open (
    ACE_Handler &handler,
    ACE_HANDLE handle,
    const void *completion_key,
    ACE_Proactor *proactor = 0
    );
```

Initializes the factory with information which will be used with each asynchronous call.  If (handle == ACE\_INVALID\_HANDLE), ACE\_Handler::handle will be called on the handler to get the correct handle.

```
int cancel (void);
```

@@ Not implemented. Returns 0.

```
ACE_Proactor* proactor (void) const;
```

Return the underlying proactor.
