Function Documentation

msg_accept_any_dup_one()

char * msg_accept_any_dup_one	(	msg_header_t *	dst,
		msg_header_t const *	src,
		char *	b,
		isize_t	xtra )

Duplicate one msg_accept_any_t object.

msg_accept_any_dup_xtra()

isize_t msg_accept_any_dup_xtra	(	msg_header_t const *	h,
		isize_t	offset )

Calculate extra memory used by accept-* headers.

msg_multipart_complete()

int msg_multipart_complete	(	su_home_t *	home,
		msg_content_type_t *	c,
		msg_multipart_t *	mp )

Add all missing parts to the multipart.

Add missing components such as boundaries between body parts, separators between body-part headers and data, and close-delimiter after last body-part to the multipart message.

Parameters

[in,out]	home	home for allocating structures
[in,out]	c	content-type header for multipart
[in,out]	mp	pointer to first multipart structure

Return values

0	when successful
-1	upon an error

Errors:

\n EBADMSG

The Content-Type header c is malformed, or multipart message contains a malformed Content-Type header.

\n ENOMEM

A memory allocation failed.

\n EINVAL

The function msg_multipart_complete() was given invalid arguments.

msg_multipart_create()

msg_multipart_t * msg_multipart_create	(	su_home_t *	home,
		char const *	content_type,
		void const *	data,
		isize_t	dlen )

Create a part for MIME multipart entity.

The function msg_multipart_create() allocates a new msg_multipart_t object from memory home home. If content_type is non-NULL, it makes a msg_content_type_t header object and adds the header to the msg_multipart_t object. If dlen is nonzero, it allocates a msg_payload_t structure of dlen bytes for the payload of the newly created msg_multipart_t object. If data is non-NULL, it copies the dlen bytes of of data to the payload of the newly created msg_multipart_t object.

Returns

A pointer to the newly created msg_multipart_t object, or NULL upon an error.

msg_multipart_parse()

msg_multipart_t * msg_multipart_parse	(	su_home_t *	home,
		msg_content_type_t const *	c,
		msg_payload_t *	pl )

Parse a MIME multipart.

The function msg_multipart_parse() parses a MIME multipart message. The common syntax of multiparts is described in RFC 2046 (section 7).

Parameters

[in,out]	home	home for allocating structures
[in]	c	content-type header for multipart
[in]	pl	payload structure for multipart

After parsing, the pl will contain the plain-text preamble (if any).

Note

If no Content-Type header is given, the msg_multipart_parse() tries to look for a suitable boundary. Currently, it takes first boundary-looking string and uses that, so it can be fooled with, for instance, signature "--Pekka".

msg_multipart_prepare()

issize_t msg_multipart_prepare	(	msg_t *	msg,
		msg_multipart_t *	mp,
		int	flags )

Encode a multipart.

Returns

The size of multipart in bytes, or -1 upon an error.
