Member Function Documentation

const void * ACE_WIN32_Asynch_Read_Dgram_Result::act void   )  const [virtual]
 

ACT associated with the operation.

Reimplemented from ACE_WIN32_Asynch_Result.

size_t ACE_WIN32_Asynch_Read_Dgram_Result::bytes_to_read void   )  const [virtual]
 

The number of bytes which were requested at the start of the asynchronous read.

Implements ACE_Asynch_Read_Dgram_Result_Impl.

size_t ACE_WIN32_Asynch_Read_Dgram_Result::bytes_transferred void   )  const [virtual]
