! 17: This module contains some local file writer streams based on the basic file
! 18: writer stream defined in the <A HREF="HTFWrite.html">HTFWrite module</a>.
! 19: They can be used to do save-as, save-and-callback etc.
! 20: <P>
! 21: This module is implemented by <A HREF="HTFSave.c">HTFSave.c</A>, and it
! 22: is a part of the <A HREF="http://www.w3.org/Library/">W3C Sample Code
! 23: Library</A>.

! 32: </H2>
! 33: <P>
! 34: This is a set of functions that can be registered as converters. They all
! 35: use the basic ANSI C file writer stream for writing out to the local file
! 36: system.

! 43: <CODE>HTSaveLocally</CODE>
! 44: <DD>
! 45: Saves a file to local disk. This can for example be used to dump date objects
! 46: of unknown media types to local disk. The stream prompts for a file name
! 47: for the temporary file.
! 48: <DT>
! 49: <CODE>HTSaveAndExecute</CODE>
! 50: <DD>
! 51: Creates temporary file, writes to it and then executes system command (maybe
! 52: an external viewer) when <CODE>EOF</CODE> has been reached. The stream finds
! 53: a suitable name of the temporary file which preserves the suffix. This way,
! 54: the system command can find out the file type from the name of the temporary
! 55: file name.
! 56: <DT>
! 57: <CODE>HTSaveAndCallback</CODE>
! 58: <DD>
! 59: This stream works exactly like the <CODE>HTSaveAndExecute</CODE> stream but
! 60: in addition when <CODE>EOF</CODE> has been reached, it checks whether a callback
! 61: function has been associated with the request object in which case, this
! 62: callback is being called. This can be use by the application to do some
! 63: processing <EM>after</EM> the system command has terminated. The callback
! 64: function is called with the file name of the temporary file as parameter.
