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.

ACE_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.
