Syntax
dataview.getInt32(byteOffset [, littleEndian])
Parameters
- byteOffset
- The offset, in bytes, from the start of the view where to read the data.
- littleEndian
- Optional Indicates whether the 32-bit int is stored in little- or big-endian format. If false or undefined, a big-endian value is read.
Return value
A signed 32-bit integer number.
Errors thrown
RangeError
- Thrown if the
byteOffset
is set such as it would read beyond the end of the view.
Description
There is no alignment constraint; multi-byte values may be fetched from any offset.
Examples
Using the getInt32
method
var buffer = new ArrayBuffer(8); var dataview = new DataView(buffer); dataview.getInt32(1); // 0
