This is PUBLIC DOMAIN. 旼컴컴컴컴컴컫컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴 � Disclaimer � 읕컴컴컴컴컴켸 DIGITAL UNDERGROUND & Alessandro Job makes no warranty of any kind, either express or implied,including but not limited to implied warranties of merchantability and fitness for a particular purpose, with respect to this software and accompanying documentation.

The name of the datafile library must be the first argument of DFMAKE. The format of the text file is very simple: you need only to write the name of the files divided by a CR,a space or a comma.If the files you need are not in the current dir,you must specify them with the full path name. Filenames in library are case sensitive. Usage: DFMAKE [library name] [-command[commandoption]] This are the commands you can use: -?,-h : show the help. -fFILELIST : this is the text file with the list of files you have to insert in the new library file. Use this option only when you want to create a library file from scratch. -aFILENAME : add file FILENAME to the top of the library.If the file is not in the current dir give full pathname. -dFILENAME : delete file FILENAME from the library. -xFILENAME : extract file FILENAME from the library to the current dir.If FILENAME = *,extract all files in library. -rOLDFILENAME NEWFILENAME : rename the file OLDFILENAME,contained in the library,in NEWFILENAME. 旼컴컴컴컴컴컴컫컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴 � Developement � 읕컴컴컴컴컴컴켸 Some routines to access a datafile library are supplyed.They are not very optimized,but they are only examples.All the functions use the PMC library functions for PMODE by Thomas Pytel. FUNCTIONS SUPPLYED: Name: WORD __cdecl df_open(STR filename); Usage: opens the 'filename' datafile library. In: filename = full name of the datafile. Out:WORD = file handle if datafile opened else NULL. Name: void __cdecl df_close(WORD df_handle); Usage: closes a previously opened datafile. In: df_handle = datafile file handle. Name: DATAFILE * __cdecl df_getinfos(WORD df_handle); Usage: get all the infos to access the files in the datafile. In: df_handle = file handle returned by df_open(); Out:DATAFILE * = a pointer to a list of DATAFILE structs containing all the infos. NULL if an error occurred. Name: void __cdecl df_delinfos(DATAFILE *datafileinfo); Usage: frees the memory allocated by df_getinfos().Use this function only when you want to have no more access to the datafile. In: datafileinfo= a pointer to the list of DATAFILE structs returned by df_getinfos(). Name: PTR __cdecl df_read(WORD df_handle,DATAFILE *datafileinfo, \ STR name,PTR buffer); Usage: reads in memory a file contained in the datafile. In: df_handle = the file handle of the datafile. datafileinfo= the pointer returned by df_getinfos(). name = the name of the file to be loaded. buffer = a pointer to a pre-allocated buffer of the size of the file to be loaded,or NULL if allocation must be done by function. Out:PTR = the pointer to the memory containing the loaded file,or NULL if error. DATA STRUCTURES: struct datafile { BYTE name[13]; // name of the file DWORD offset; // positive offset from the file's end DWORD length; // lenght in bytes of the file struct datafile *next; // next file info structure or NULL }; typedef struct datafile DATAFILE; This is the structure used to store the infos for every file in the datafile. 旼컴컴컴컴컴컴컴컴컴컴컴컴쩡컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴 � DATAFILE library format � 읕컴컴컴컴컴컴컴컴컴컴컴컴� This is the format of a datafile file made by DFMAKE. All offsets are positive offsets from the end of the datafile.
