Destructor.
.PP
.SH MEMBER FUNCTION DOCUMENTATION
.PP 
.SS const void * ACE_WIN32_Asynch_Read_File_Result::act (void) const
.PP
ACT associated with the operation.
.PP
Reimplemented from \fBACE_WIN32_Asynch_Read_Stream_Result\fR.
.SS u_long ACE_WIN32_Asynch_Read_File_Result::bytes_to_read (void) const
.PP
The number of bytes which were requested at the start of the asynchronous read.
.PP
Reimplemented from \fBACE_WIN32_Asynch_Read_Stream_Result\fR.
.SS u_long ACE_WIN32_Asynch_Read_File_Result::bytes_transferred (void) const
.PP
Number of bytes transferred by the operation.
.PP
Reimplemented from \fBACE_WIN32_Asynch_Read_Stream_Result\fR.
.SS void ACE_WIN32_Asynch_Read_File_Result::complete (u_long bytes_transferred, int success, const void * completion_key, u_long error)\fC [protected, virtual]\fR
.PP
\fBACE_Proactor\fR will call this method when the read completes.
.PP
Reimplemented from \fBACE_WIN32_Asynch_Read_Stream_Result\fR.
.SS const void * ACE_WIN32_Asynch_Read_File_Result::completion_key (void) const
.PP
This returns the ACT associated with the handle when it was registered with the I/O completion port. This ACT is not the same as the ACT associated with the asynchronous operation. 
.PP
Reimplemented from \fBACE_WIN32_Asynch_Read_Stream_Result\fR.
.SS u_long ACE_WIN32_Asynch_Read_File_Result::error (void) const
.PP
Error value if the operation fail.
.PP
Reimplemented from \fBACE_WIN32_Asynch_Read_Stream_Result\fR.
.SS ACE_HANDLE ACE_WIN32_Asynch_Read_File_Result::event (void) const
.PP
Event associated with the \fBOVERLAPPED\fR structure.
.PP
Reimplemented from \fBACE_WIN32_Asynch_Read_Stream_Result\fR.
.SS ACE_HANDLE ACE_WIN32_Asynch_Read_File_Result::handle (void) const
.PP
I/O handle used for reading.
.PP
Reimplemented from \fBACE_WIN32_Asynch_Read_Stream_Result\fR.
.SS \fBACE_Message_Block\fR & ACE_WIN32_Asynch_Read_File_Result::message_block (void) const
.PP
Message block which contains the read data.
.PP
Reimplemented from \fBACE_WIN32_Asynch_Read_Stream_Result\fR.
.SS u_long ACE_WIN32_Asynch_Read_File_Result::offset (void) const
.PP
This really make sense only when doing file I/O.
.PP
Reimplemented from \fBACE_WIN32_Asynch_Read_Stream_Result\fR.
.SS u_long ACE_WIN32_Asynch_Read_File_Result::offset_high (void) const
.PP
Offset_high associated with the \fBOVERLAPPED\fR structure.
.PP
Reimplemented from \fBACE_WIN32_Asynch_Read_Stream_Result\fR.
.SS int ACE_WIN32_Asynch_Read_File_Result::post_completion (\fBACE_Proactor_Impl\fR * proactor)
.PP
Post <this> to the Proactor's completion port.
.PP
Reimplemented from \fBACE_WIN32_Asynch_Read_Stream_Result\fR.
.SS int ACE_WIN32_Asynch_Read_File_Result::priority (void) const
.PP
The priority of the asynchronous operation. Currently, this is not supported on Win32.
.PP
Reimplemented from \fBACE_WIN32_Asynch_Read_Stream_Result\fR.
.SS int ACE_WIN32_Asynch_Read_File_Result::signal_number (void) const
.PP
No-op. Returns 0.
