This header file contains one function

• "ccommand," which helps you port a program that relies on command-line arguments.
• "clrscr," clears the SIOUX window and flushes the buffer.
• "getch" returns the keyboard character pressed when an ascii key is pressed
• "InstallConsole" installs the Console package.
• "kbhit" returns true if any keyboard key is pressed without retrieving the key
• "ReadCharsFromConsole" reads from the Console into a buffer.
• "RemoveConsole" removes the console package.
• "__ttyname" Returns the name of the terminal associated with the file id. The unix.h function ttyname calls this function
• "WriteCharsToConsole" writes a stream of output to the Console window.

If you're porting a UNIX or DOS program, you might also need the functions in other UNIX compatibility headers.
