mutt_pattern_exec()

bool mutt_pattern_exec	(	struct Pattern *	pat,
		PatternExecFlags	flags,
		struct Mailbox *	m,
		struct Email *	e,
		struct PatternCache *	cache )

Match a pattern against an email header.

Parameters

pat	Pattern to match
flags	Flags, e.g. MUTT_MATCH_FULL_ADDRESS
m	Mailbox
e	Email
cache	Cache for common Patterns

Return values

true	Success, pattern matched
false	Pattern did not match

flags: MUTT_MATCH_FULL_ADDRESS: match both personal and machine address cache: For repeated matches against the same Header, passing in non-NULL will store some of the cacheable pattern matches in this structure.

mutt_pattern_alias_exec()

bool mutt_pattern_alias_exec	(	struct Pattern *	pat,

Parameters

pat	Pattern to match
flags	Flags, e.g. MUTT_MATCH_FULL_ADDRESS
av	AliasView
cache	Cache for common Patterns

Return values

true	Success, pattern matched
false	Pattern did not match
