1.2 Vector data of uint8. Note: the data vector must contain 0 to indicate NULL terminate string, example: uint8(['file1.txt' 0])

2. Append

0 : Data write position start at 0 after open file.

non-zero :  Data append to last file position.

3. Data

4 Close

0 : Do not close file after write.

non-zero : Close file after write.
