lfcbase 18.11.2012 1.3.4 Version released
lfcbase 16.11.2012 1.3.4 In the method File::writeByte, the case was untreated that the write system call writes less than the number of bytes given. To handle this siuation, the method was expanded to repeat the write call untill all bytes have been written -------- if ( ( numbyte = ::write(_fd, buf, bufsize)) == -1 ) { Chain msg = Chain("Write system error for ") + _filename + Chain(" : ") + Chain(strerror(errno)); throw Exception(EXLOC, msg); } while ( numbyte < bufsize ) { unsigned long n; if ( ( n = ::write(_fd, (char*)((unsigned long)buf + numbyte), bufsize - numbyte)) == -1 ) { Chain msg = Chain("Write system error for ") + _filename + Chain(" : ") + Chain(strerror(errno)); throw Exception(EXLOC, msg); } numbyte += n; }
