I used the code of Inflate.c in TZipBuilderSFX component. During test of this component CodeGuard reported a memory leak of memory blocs created with malloc in the function 'huft_build(..)' called from inflate_fixed. After adding : huft_free(fixed_tl); huft_free(fixed_td); at the end of the function inflate_fixed just after inflate_codes(fixed_tl, fixed_td, fixed_bl, fixed_bd); CodeGuard did not report any errors HTH Roger Aelbrecht http://web.wanadoo.be/driehoeksw ----------- To unsubscribe from this list, send an empty e-mail message to: delphizip-request@xxxxxxxxxxxxx and put the word unsubscribe in the subject.
