BinaryWrite

writes a byte of data, specified as an integer from 0 to 255.

BinaryWrite

writes a sequence of bytes.

BinaryWrite

writes the raw sequence of characters in a string.

BinaryWrite

writes an object of the specified type.

BinaryWrite

writes a sequence of objects of the specified type.

BinaryWrite

writes a sequence of objects with a sequence of types.

MORE INFORMATION

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 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.
