/* 
** 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
