BinaryWrite
 Usage
• BinaryWrite[channel, b] writes a byte of data, specified as an integer from 0 to 255.
• BinaryWrite[channel, { ,  , ... }] 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, { ,  , ... }, type] writes a sequence of objects of the specified type.
• BinaryWrite[channel, { ,  , ... }, { ,  , ... }] writes a sequence of objects with a sequence of types.
Notes
• BinaryWrite supports the same types as BinaryRead. • The output channel used by BinaryWrite can be a single file or pipe, or list of them, each specified by a string giving their 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 option can be given: • BinaryWrite[channel, "string"] uses type "Character8", so all characters in "string" should have character code in the range 0-255. • BinaryWrite returns $Failed if it encounters a data element that cannot match the type specified. • New in Version 5.1.
