io_out( ) Built-in Function
The io_out( ) built-in function writes data to an I/O object.
The <io_types.h> include file contains optional type definitions for each of the I/O
object types. The type names are the I/O object type name followed by “_t”. For
example bit_t is the type name for a bit I/O object. The data type of output-value
is listed below for each object type.

Syntax
return-value io_out ( output-io-object-name , output-value [, args ]);
return-value The value returned by the function. void for all models
except i2c (for which return-value is a Boolean value).
