err	Where to write error messages

Return values

CommandResult

Result e.g. MUTT_CMD_SUCCESS

set_dump()

enum CommandResult set_dump	(	ConfigDumpFlags	flags,
		struct Buffer *	err
	)

Dump list of config variables into a file/pager.

Parameters

flags	what configs to dump: see ConfigDumpFlags
err	buffer for error message

Returns

num See CommandResult

FIXME: Move me into parse/set.c. Note: this function currently depends on pager, which is the reason it is not included in the parse library.
