Print a file.
Print a file.Works exactly like out_printfile(). This function, however, puts the terminal in non-blocking mode. The user may press a special control character (Enter, New Line, Line Feed, Escape, Control-C or Control-O) to stop the transmission. The terminal is reset to its previous mode of operation after the function finishes, using inp_resetblocking(). Do not use this latter function with out_printlongfile().
