| nOffset | (Long) Defines the position of read value in the data block. The read value must be inside the data block. The item is read either whole or not read at all. >= 0 - Index (in bytes, zero-based index) in data block. -4 - The internal automatic position is used (see AutoOffset). It points behind the last read or written value and increases continually. If the items are read/written one by one then it is not necessary to define the position, but it is better to use this automated positioning. |
|---|---|
| sFile | (String) The file name with the path. If a full path is not entered, then it is completed relative to the application folder. It is recommended to use the PROMOTIC path syntax - see PROMOTIC path to files and folders. |
| nFileOffset | [optional] (Long) Defines the position of written value in the binary file in bytes. The value 0 (default) means writing from beginning of the file. |
| nLength | [optional] (Long) Defines the number of written bytes. >=0 - Number (count) in bytes -1 (default) - Writing all values up to the end of the data block. -2 - Writing all values up to the end of the data block and then sets the end of the file. |
