std.io Package
Function Description
The io package provides the capability of data exchange between a program and an external device.
I/O operation refers to an operation of exchanging data between a program and an external device. Cangjie provides universal interfaces and some special implementations for streaming I/O operations. An input or output stream is similar to a data channel and carries a segment of ordered data. A program reads data (from a file or network) in the input stream and writes data to the output stream (to a file or network).
