Detailed Description

Defines an active connection factory for the ACE_FILE wrappers.

Note that the O_APPEND flag is only partly supported on Win32. If you specify O_APPEND, then the file pointer will be positioned at the end of the file initially during open, but it is not re-positioned at the end prior to each write, as specified by POSIX. This is generally good enough for typical situations, but it is ``not quite right'' in its semantics.

Constructor & Destructor Documentation

ACE_FILE_Connector::ACE_FILE_Connector (  void    )

Default constructor.

ASYS_INLINE ACE_FILE_Connector::ACE_FILE_Connector (  ACE_FILE_IO &    new_io, const ACE_FILE_Addr &    remote_sap, ACE_Time_Value *    timeout = 0, const ACE_Addr &    local_sap = ACE_Addr::sap_any, int    reuse_addr = 0, int    flags = O_RDWR|O_CREAT, int    perms = ACE_DEFAULT_FILE_PERMS )

Actively ``connect'' and produce a <new_io> <ACE_FILE_IO> object if things go well. The <remote_sap> is the file that we are trying to create/open. If it's the default value of <ACE_Addr::sap_any> then the user is letting the OS create the filename (via <ACE_OS::mktemp>). The <timeout> is the amount of time to wait to create/open the file. If it's 0 then we block indefinitely. If *timeout == {0, 0} then the file is created using non-blocking mode. In this case, if the create/open can't be done immediately the value of -1 is returned with <errno == EWOULDBLOCK>. If *timeout > {0, 0} then this is the maximum amount of time to wait before timing out. If the time expires before the connection is made <errno == ETIME>. The <local_sap> and <reuse_addr> parameters are ignored. The <flags> and <perms> arguments are passed down to the <ACE_OS::open> method.

void ACE_FILE_Connector::dump (  void    )  const

Dump the state of an object.

ASYS_INLINE int ACE_FILE_Connector::reset_new_handle (  ACE_HANDLE    handle )

Resets any event associations on this handle.
