.Sh DESCRIPTION
The
.Fn bsde_parse_rule
function parses an argument vector
(e.g.\&
.Fa argv
as passed to
.Fn main )
into
.Fa rule .
If an error occurs,
.Fa *errstr
is filled in with the error string
(up to
.Fa errlen
characters, including the terminating
.Dv NUL ) .
.Pp
The
.Fn bsde_parse_rule_string
function is identical to
.Fn bsde_parse_rule ,
except that it parses a single string rather than an array of arguments.
.Sh RETURN VALUES
The
.Fn bsde_parse_rule_string
and
.Fn bsde_parse_rule
functions return 0 if successful;
otherwise the value \-1 is returned and the value of
.Fa *errstr
is filled in as documented in
.Sx DESCRIPTION .
