+.
+.Sh DESCRIPTION
+Returns the sliding dictionary
+being maintained by deflate.
+.Fa dictLength
+is set to the number of bytes in the dictionary,
+and that many bytes are copied to
+.Fa dictionary .
+.Fa dictionary
+must have enough space,
+where 32768 bytes is always enough.
+If
+.Fn deflateGetDictionary
+is called with
+.Fa dictionary
+equal to
+.Dv Z_NULL,
+then only the dictionary length is returned,
+and nothing is copied.
+Similarly,
+if
+.Fa dictLength
+is
+.Dv Z_NULL ,
+then it is not set.
+.
+.Pp
+.Fn deflateGetDictionary
+may return a length less than the window size,
+even when more than the window size in input
+has been provided.
+It may return up to 258 bytes less in that case,
+due to how zlib's implementation of deflate
+manages the sliding window and lookahead for matches,
+where matches can be up to 258 bytes long.
+If the application needs the last window-size bytes of input,
+then that would need to be saved by the application
+outside of zlib.
