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. */ class ACE_FILE_Connector { public: / Default constructor. ACE_FILE_Connector ();

/** 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::mkstemp>). 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. If *timeout > {0, 0} then this is the maximum amount of time to wait before timing out. The local_sap and reuse_addr parameters are ignored. The flags and perms arguments are passed down to the <ACE_OS::open> method. */ 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);
