Inheritance diagram for ACE_WIN32_Asynch_Write_File_Result
Public Methods | |
u_long | bytes_transferred (void) const |
Number of bytes transferred by the operation. | |
const void* | act (void) const |
ACT associated with the operation. | |
int | success (void) const |
Did the operation succeed? | |
const void* | completion_key (void) const |
u_long | error (void) const |
Error value if the operation fail. | |
ACE_HANDLE | event (void) const |
Event associated with the OVERLAPPED structure. | |
u_long | offset (void) const |
This really make sense only when doing file I/O. | |
u_long | offset_high (void) const |
Offset_high associated with the OVERLAPPED structure. | |
int | priority (void) const |
The priority of the asynchronous operation. Currently, this is not supported on Win32. | |
int | signal_number (void) const |
No-op. Returns 0. | |
u_long | bytes_to_write (void) const |
The number of bytes which were requested at the start of the asynchronous write. | |
ACE_Message_Block& | message_block (void) const |
Message block that contains the data to be written. | |
ACE_HANDLE | handle (void) const |
I/O handle used for writing. | |
int | post_completion (ACE_Proactor_Impl *proactor) |
Post <this> to the Proactor's completion port. | |
Protected Methods | |
ACE_WIN32_Asynch_Write_File_Result (ACE_Handler &handler, ACE_HANDLE handle, ACE_Message_Block &message_block, u_long bytes_to_write, const void* act, u_long offset, u_long offset_high, ACE_HANDLE event, int priority, int signal_number = 0) | |
virtual void | complete (u_long bytes_transferred, int success, const void *completion_key, u_long error) |
ACE_Proactor will call this method when the write completes. | |
virtual | ~ACE_WIN32_Asynch_Write_File_Result (void) |
Destructor. | |
Friends | |
class | ACE_WIN32_Asynch_Write_File |
class | ACE_WIN32_Proactor |
This class has all the information necessary for the <handler> to uniquiely identify the completion of the asynchronous write.
This class differs slightly from ACE_Asynch_Write_Stream::Result as it calls back on the <handler> instead of . No additional state is required by this class as ACE_Asynch_Result can store the <offset>.

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. Reimplemented from ACE_WIN32_Asynch_Write_Stream_Result. |
