The internal representation is zero (false) +/* and non-zero (true). The external representation is "no" +/* (false) and "yes" (true). The conversion from external +/* representation is case insensitive. Unlike mail_conf_bool(3) +/* the default is a string value which is subject to macro expansion. +/* +/* get_mail_conf_nbool() looks up the named entry in the global +/* configuration dictionary. The specified default value is +/* returned when no value was found. +/* +/* get_mail_conf_nbool_fn() is similar but specifies a function that +/* provides the default value. The function is called only +/* when the default value is needed. +/* +/* set_mail_conf_nbool() updates the named entry in the global +/* configuration dictionary. This has no effect on values that +/* have been looked up earlier via the get_mail_conf_XXX() routines. +/* +/* get_mail_conf_nbool_table() and get_mail_conf_int_fn_table() initialize +/* lists of variables, as directed by their table arguments. A table +/* must be terminated by a null entry. +/* DIAGNOSTICS +/* Fatal errors: malformed boolean value. +/* SEE ALSO +/* config(3) general configuration +/* mail_conf_str(3) string-valued configuration parameters +/* mail_conf_int(3) integer-valued configuration parameters +/* LICENSE +/* .ad +/* .fi +/* The Secure Mailer license must be distributed with this software. +/* AUTHOR(S) +/* Wietse Venema +/* IBM T.J.
