- Here is a list of all types, function and procedures implemented in the
- WWP_DATA 1.0 unit:
-
- type file_ww;
- type of WWPACK data files.
- Use this type insted of 'file' type!
-
- function ioresult_ww:byte;
- this function returns the status of last I/O operation on the WWPACKed
- data file.
- Standard I/O codes: please see the Turbo Pascal documentation.
- Extended I/O codes:
- 250 - the file is not a WWPACKed data file.
- 251 - unrecognized version of WWPACKed data file.
- Extended I/O code may be set while opening the file (reset_ww function).
- In case of any Extended I/O errors the file will not be open!
-
- procedure assign_ww(var f:file_ww;filename:string);
- this procedure assigns the name of a file to the file_ww variable.
- Please use it to initialize the file you want to read.
-
- procedure reset_ww(var f:file_ww);
- opens assigned file for reading.
-
- procedure close_ww(var f:file_ww);
- closes an opened file.
-
- procedure seek_ww(var f:file_ww;offset:longint);
- sets the current position of a file to 'offset' value.
- See filepos_ww function.
-
- function filesize_ww(var f:file_ww):longint;
- returns the size of a compressed file.
- Warning: this function returns the size of a data stored in the file,
- not the real file size! That means, that the value returned with
- this function is bigger than the real file size!
-
- function filepos_ww(var f:file_ww):longint;
- returns the current position of a file.
-
- procedure blockread_ww(var f:file_ww;var buf;to_read:word;var result:word);
- this procedure reads 'to_read' bytes to the 'buf' from 'f' file.
- After operation the 'result' contains number of read bytes.
-
-
-
- WWP_DATA unit is saved in two files. Please choose one:
-
- WWP_DATA.TPU for Turbo Pascal 7.0
- WWP_DATA.T60 for Turbo Pascal 6.0 (rename to WWP_DATA.TPU)
