Members
| Parameters | Description |
|---|---|
file | This is the ID of a previously opened file, as returned by the fsIOOpen function. |

byteOffset | This is the offset into the file to which data will be written. |
byteToWrite | This defines the number of bytes to write to the file. |

Remarks
This function is non-blocking: it will not wait for the file to be read to pass to the next line of code.
