Number of bytes or characters actually read.

Result2 : Buffer

Result data.

open_id : integer

The syntax 1 is better because it translates the data into the provided datatype (from or to Unicode if necessary), whenever the open mode.

The number given for <length> and of the result is the "natural" length, which will be:

For syntax 1:

• a number of bytes if the the 3^rd parameter datatype is binary or text

• a number of characters if the 3^rd parameter datatype is Unicode

For syntax 2:

• a number of bytes if the open mode is binary or text

• a number of Unicode characters if the open mode is Unicode
