* include/hbchksum.h
* src/rtl/hbmd5.c
* changed C function:
void hb_md5file( HB_FHANDLE hFile, char * digest )
to
HB_BOOL hb_md5file( const char * pszFileName, char * digest )
Warning: [INCOMPATIBLE]
* src/rtl/copyfile.c
* src/rtl/fscopy.c
* src/rtl/hbmd5.c
* src/rtl/isprint.c
* src/rtl/memofile.c
* changed hb_fs*() API to hb_file*() API
* contrib/hbnetio/netiocli.c
! fixed GPF when non attributes are passed to hb_fileDirectory()
redirected to NETIO - thanks to Rolf for the info about the problem.
* contrib/hbnetio/netiosrv.c
! allow to pass empty directory to hb_fileDirectory() redirected to NETIO
