writes a sequence of bytes.

BinaryWrite[channel, "string"]
writes the raw sequence of characters in a string.

BinaryWrite[channel, x, type]
writes an object of the specified type.

BinaryWrite[channel, {x₁, x₂, ...}, type]
writes a sequence of objects of the specified type.

BinaryWrite[channel, {x₁, x₂, ...}, {type₁, type₂, ...}]

Details and Options Details and Options

BinaryWrite supports the same types as BinaryRead.
The output channel used by BinaryWrite can be a single file or pipe, or a list of them, each specified by a string giving its name, or by an OutputStream object that has been opened with BinaryFormat->True.
If any of the specified files or pipes are not already open, BinaryWrite calls OpenWrite to open them.
BinaryWrite does not close files and pipes after it finishes writing to them.
When a list of types is given, the list is effectively repeated as many times as necessary.
The following options can be given:
ByteOrdering $ByteOrdering what byte ordering to use
BinaryWrite[channel, "string"] uses type , so all characters in should have character codes in the range 0-255.
BinaryWrite returns $Failed if it encounters a data element that cannot match the type specified.
