.Sh DESCRIPTION
The
.Fn getsubopt
function
-parses a string containing tokens delimited by one or more tab, space or
-comma
+parses a string containing tokens that are delimited
+by one or more tab, space, or comma
.Pq Ql \&,
characters.
-It is intended for use in parsing groups of option arguments provided
-as part of a utility command line.
+It is intended for use in parsing groups of option arguments
+that are provided as part of a utility command line.
.Pp
The argument
.Fa optionp
is a pointer to a pointer to the string.
The argument
-.Fa tokens
+.Fa keylistp
is a pointer to a
.Dv NULL Ns -terminated
array of pointers to strings.
.Fn getsubopt
function
returns the zero-based offset of the pointer in the
-.Fa tokens
-array referencing a string which matches the first token
-in the string, or, \-1 if the string contains no tokens or
-.Fa tokens
+.Fa keylistp
+array, referencing a string which matches the first token in the string
+ or \-1 if the string contains no tokens or
+.Fa keylistp
does not contain a matching string.
.Pp
If the token is of the form ``name=value'', the location referenced by
if no ``value'' portion was present.
