attach_forward_msgs()

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

static

Forward one or several message-type attachments.

Parameters

fp	File handle to attachment
actx	Attachment Context
b	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.
