1.20 +** Win16 stdio special case.
1.21 +** To get stdio to work for Win16, all calls to printf() and related
1.22 +** things must be called from the environment of the .EXE; calls to
1.23 +** printf() from the .DLL send output to the bit-bucket.
1.24 +**
1.25 +** To make sure that PR_fprintf(), and related functions, work correctly,
1.26 +** the actual stream I/O to stdout, stderr, stdin must be done in the
1.27 +** .EXE. To do this, a hack is placed in _MD_Write() such that the
1.28 +** fd for stdio handles results in a call to the .EXE.
1.29 +**
1.30 +** file w16stdio.c contains the functions that get called from NSPR
1.31 +** to do the actual I/O. w16stdio.o must be statically linked with
1.32 +** any application needing stdio for Win16.
1.33 +**
1.34 +** The address of these functions must be made available to the .DLL
1.35 +** so he can call back to the .EXE. To do this, function
1.36 +** PR_MD_RegisterW16StdioCallbacks() is called from the .EXE.
1.37 +** The arguments are the functions defined in w16stdio.c
1.38 +** At runtime, MD_Write() calls the registered functions, if any
1.39 +** were registered.
1.40 +**
1.41 +** prinit.h contains a macro PR_STDIO_INIT() that calls the registration
1.42 +** function for Win16; For other platforms, the macro is a No-Op.
1.43 +**
1.44 +** Note that stdio is not operational at all on Win16 GUI applications.
1.45 +** This special case exists to provide stdio capability from the NSPR
1.46 +** .DLL for command line applications only. NSPR's test cases are
1.47 +** almost exclusively command line applications.
