+.SH DESCRIPTION
+.TP
+.I regex_t
+This is a structure type used in regular expression matching.
+It holds a compiled regular expression,
+compiled with
+.BR regcomp (3).
+.TP
+.I regmatch_t
+This is a structure type used in regular expression matching.
+.TP
+.I regoff_t
+According to POSIX,
+it shall be a signed integer type
+capable of storing the largest value that can be stored in either an
+.I ptrdiff_t
+type or a
+.I ssize_t
+type.
+.SH VERSIONS
+Prior to POSIX.1-2008,
+the type was
+capable of storing the largest value that can be stored in either an
+.I off_t
+type or a
+.I ssize_t
+type.
+.SH CONFORMING TO
+POSIX.1-2001 and later.
