+** Win16 stdio special case.
+** To get stdio to work for Win16, all calls to printf() and related
+** things must be called from the environment of the .EXE; calls to
+** printf() from the .DLL send output to the bit-bucket.
+**
+** To make sure that PR_fprintf(), and related functions, work correctly,
+** the actual stream I/O to stdout, stderr, stdin must be done in the
+** .EXE. To do this, a hack is placed in _MD_Write() such that the
+** fd for stdio handles results in a call to the .EXE.
+**
+** file w16stdio.c contains the functions that get called from NSPR
+** to do the actual I/O. w16stdio.o must be statically linked with
+** any application needing stdio for Win16.
+**
+** The address of these functions must be made available to the .DLL
+** so he can call back to the .EXE. To do this, function
+** PR_MD_RegisterW16StdioCallbacks() is called from the .EXE.
+** The arguments are the functions defined in w16stdio.c
+** At runtime, MD_Write() calls the registered functions, if any
+** were registered.
+**
+** prinit.h contains a macro PR_STDIO_INIT() that calls the registration
+** function for Win16; For other platforms, the macro is a No-Op.
+**
+** Note that stdio is not operational at all on Win16 GUI applications.
+** This special case exists to provide stdio capability from the NSPR
+** .DLL for command line applications only. NSPR's test cases are
+** almost exclusively command line applications.
+**
+** See also: w16io.c, w16stdio.c
