Basic ANSI C File Writer Stream

This module contains some local file writer streams based on the basic file writer stream defined in the HTFWrite module. They can be used to do save-as, save-and-callback etc.

This module is implemented by HTFSave.c, and it is a part of the W3C Sample Code Library.

Various Converters using the File Writer Stream

This is a set of functions that can be registered as converters. They all use the basic ANSI C file writer stream for writing out to the local file system.

extern HTConverter HTSaveAndExecute, HTSaveLocally, HTSaveAndCallback;

Saves a file to local disk. This can for example be used to dump date objects of unknown media types to local disk. The stream prompts for a file name for the temporary file.
Creates temporary file, writes to it and then executes system command (maybe an external viewer) when EOF has been reached. The stream finds a suitable name of the temporary file which preserves the suffix. This way, the system command can find out the file type from the name of the temporary file name.
This stream works exactly like the HTSaveAndExecute stream but in addition when EOF has been reached, it checks whether a callback function has been associated with the request object in which case, this callback is being called. This can be use by the application to do some processing after the system command has terminated. The callback function is called with the file name of the temporary file as parameter.
