MIME Parser

The MIME parser stream presents a MIME document. It recursively invokes the format manager to handle embedded formats.

As well as stripping off and parsing the headers, the MIME parser has to parse any weirld MIME encodings it may meet within the body parts of messages, and must deal with multipart messages.

This module is implemented to the level necessary for operation with WWW, but is not currently complete for any arbitrary MIME message.

Check the source for latest additions to functionality.

The MIME parser is complicated by the fact that WWW allows real binary to be sent, not ASCII encoded. Therefore the netascii decoding is included in this module. One cannot layer it by converting first from Net to local text, then decoding it. Of course, for local files, the net ascii decoding is not needed. There are therefore two creation routines.

This module is implemented by HTMIME.c, and it is a part of the W3C Reference Library.

Stream Converters in this Module

MIME header parser stream

This stream parses a complete MIME header and if a content type header is found then the stream stack is called. Any left over data is pumped right through the stream.
extern HTConverter HTMIMEConvert;

MIME Header ONLY parser stream

This stream parses a complete MIME header and then returnes HT_PAUSE. It does not set up any streams and resting data stays in the buffer. This can be used if you only want to parse the headers before you decide what to do next. This is for example the case in a server app.
extern HTConverter HTMIMEHeader;

MIME Footer ONLY parser

Parse only a footer, for example after a chunked encoding.
extern HTConverter HTMIMEFooter;
