BUILT-IN MATHEMATICA SYMBOL

BinaryRead

BinaryRead[stream]
reads one byte of raw binary data from an input stream, and returns an integer from 0 to 255.

BinaryRead[stream, type]
reads an object of the specified type.

BinaryRead[stream, {type₁, type₂, ...}]
reads a sequence of objects of the specified types.

The first argument to BinaryRead can be InputStream["name", n], or simply if there is only one open input stream with the specified name.
You can open a file or pipe to get an InputStream object using OpenRead.
Streams for use with BinaryRead should be opened with BinaryFormat->True.
There is always a "current point" maintained for any stream. When you read an object from a stream, the current point is left after the input you read. Successive calls to BinaryRead can therefore be used to read successive objects in a stream such as a file.
BinaryRead returns EndOfFile if you are at the end of the file.
BinaryRead returns Infinity for IEEE "infinity", and Indeterminate for IEEE "not-a-number".
The following options can be given:
ByteOrdering $ByteOrdering what byte ordering to use

Path $Path the path to search for files to be opened
