attach_forward_msgs()

static void attach_forward_msgs ( FILE *  fp, struct AttachCtx *  actx, struct Body *  cur, SendFlags  flags  )

static

Forward one or several message-type attachments.

Parameters

fp	File handle to attachment
actx	Attachment Context
cur	Attachment to forward (OPTIONAL)
flags	Send mode, see SendFlags

This is different from the previous function since we want to mimic the index menu's behavior.

Code reuse from mutt_send_message() is not possible here - it relies on a context structure to find messages, while, on the attachment menu, messages are referenced through the attachment index.

attach_reply_envelope_defaults()

static int attach_reply_envelope_defaults ( struct Envelope *  env, struct AttachCtx *  actx, struct Email *  parent, SendFlags  flags  )

static

Create the envelope defaults for a reply.

Parameters

env	Envelope to fill in
actx	Attachment Context
parent	Parent Email
flags	Flags, see SendFlags

Return values

0	Success
-1	Error

This function can be invoked in two ways.

Either, parent is NULL. In this case, all tagged bodies are of a message type, and the header information is fetched from them.

Or, parent is non-NULL. In this case, cur is the common parent of all the tagged attachments.

Note that this code is horribly similar to envelope_defaults() from send.c.
