I accept your point, so the following is not an argument, but just for
interest's sake I am posting this quote from "Microsoft FCI/FDI Library
"The pfnopen, pfnread, pfnwrite, pfnclose, and pfnseek parameters should
point to functions which perform file open, file read, file write, file
close, and file seek operations respectively. These functions should
accept parameters identical to those for the standard _open, _read, _write,
_close, and _lseek functions, and should likewise have identical return
I looked at the two function prototypes that I reviewed for these standard
functions in our include/msvcrt/io.h and noted that they are constified.
But yes, I shall check the public header, in future.
