mutt_fqdn()

const char * mutt_fqdn	(	bool	may_hide_host,
		const struct ConfigSubset *	sub )

Get the Fully-Qualified Domain Name.

Parameters

may_hide_host	If true, hide the hostname (leaving just the domain)
sub	Config Subset

Return values

ptr	string pointer into Hostname
NULL	Error, e.g no Hostname

Warning

Do not free the returned pointer

mutt_lookup_mime_type()

enum ContentType mutt_lookup_mime_type	(	struct Body *	b,
		const char *	path )

Find the MIME type for an attachment.

Parameters

b	Email with attachment
path	Path to attachment

Return values

enum	ContentType, e.g. TYPE_IMAGE

Given a file at 'path', see if there is a registered MIME type. Returns the major MIME type, and copies the subtype to "d". First look in a system mime.types if we can find one, then look for ~/.mime.types. The longest match is used so that we can match 'ps.gz' when 'gz' also exists.
