+.SH DESCRIPTION
+.rs
+.sp
+This function is part of an experimental set of pattern conversion functions.
+It frees the memory occupied by a converted pattern that was obtained by
+calling \fBpcre2_pattern_convert()\fP with arguments that caused it to place
+the converted pattern into newly obtained heap memory. If the argument is NULL,
+the function returns immediately without doing anything.
+.P
+The pattern conversion functions are described in the
+.\" HREF
+\fBpcre2convert\fP
+.\"
+documentation.
