Constructor & Destructor Documentation

ACE_POSIX_Asynch_Read_File_Result::ACE_POSIX_Asynch_Read_File_Result (  const ACE_Handler::Proxy_Ptr &  handler_proxy,
ACE_HANDLE  handle,
ACE_Message_Block &  message_block,

const void *  act,
u_long  offset,
u_long  offset_high,
ACE_HANDLE  event,
int  priority,
