+.Sh DESCRIPTION
+The
+.Fn devname
+function returns a pointer to the name of the block or character
+device in
+.Dq Pa /dev
+with a device number of
+.Fa dev ,
+and a file type matching the one encoded in
+.Fa type
+which must be one of
+.Dv S_IFBLK
+or
+.Dv S_IFCHR .
+If no device matches the specified values, or no information is
+available, NULL is returned.
+.Pp
+The
+.Fn devname
+function uses a static buffer, which will be overwritten
+on subsequent calls.
+The
+.Fn devname_r
+functions takes a buffer and length as arguments to avoid this problem.
+.Pp
+The traditional display for applications when no device is
+found is the string
+.Dq ?? .
