Top: Streams: Standard input, output and error devices

#include <pstreams.h>

instm  pin;
outstm pout;
outstm perr;
outstm pnull;

PTypes declares four static stream objects for standard input, output, error and null devices - pin, pout, perr and pnull respectively. These objects can be used in place of the standard C or C++ input/output interfaces. Pnull is an output stream that discards any data written to it. The putf() method in standard output objects pout and perr is atomic with respect to multithreading.
