NAME
    SetVBuf -- set buffering modes and size (V36)

SYNOPSIS
    error = SetVBuf(fh, buff, type, size)
    D0              D1   D2    D3    D4

    LONG SetVBuf(BPTR, STRPTR, LONG, LONG)

FUNCTION
    Changes the buffering modes and buffer size for a filehandle.
    With buff == NULL, the current buffer will be deallocated and a
    new one of (approximately) size will be allocated.  If buffer is
    non-NULL, it will be used for buffering and must be at least
    max(size,208) bytes long.  If buff is NULL and size is -1,
    then only the buffering mode will be changed.

INPUTS
    fh   - Filehandle
    buff - buffer pointer for buffered I/O
    type - buffering mode (see <dos/stdio.h>)
    size - size of buffer for buffered I/O (sizes less than 208 bytes
           will be ignored).

RESULT
    error - 0 if successful.  NOTE: opposite of most dos functions!

BUGS
    Not implemented yet, always returns 0.
