__readfn and __writefn parameter to match new definition of FILE's _read and _write methods. (_funopen_r): Ditto. (funopen): Ditto. (_funopen_r): Ditto. * libc/include/sys/config.h (_READ_WRITE_BUFSIZE_TYPE) Define as type int if not already defined. Add comment to explain. * libc/include/sys/reent.h: Include stddef.h. (struct __sFILE): Change type of last parameter in declaration of _read and _write methods to _READ_WRITE_BUFSIZE_TYPE. (struct __sFILE64): Ditto. * libc/stdio/local.h (__sread): Declare with last parameter set to _READ_WRITE_BUFSIZE_TYPE. (__seofread): Ditto. (__swrite): Ditto. (__swrite64): Ditto. * libc/stdio/fvwrite.c (__sfvwrite_r): Change type of local variables w and s to _READ_WRITE_RETURN_TYPE. * libc/stdio/fflush.c (__sflush_r): Change type of local variables n and t to _READ_WRITE_BUFSIZE_TYPE and _READ_WRITE_RETURN_TYPE. Add local variables flags to keep _flags value. * libc/stdio/fmemopen.c (fmemreader): Align to above change. (fmemwriter): Ditto. * libc/stdio/fopencookie.c (fcreader): Ditto. (fcwriter): Ditto. * libc/stdio/funopen.c (funread): Ditto. (funwrite): Ditto. (funreader): Ditto. (funwriter): Ditto. * libc/stdio/open_memstream.c (memwriter): Ditto. * libc/stdio/stdio.c (__sread): Ditto. (__seofread): Ditto. (__swrite): Ditto. * libc/stdio64/stdio64.c (__swrite64): Ditto.
