The standard does not require that setvbuf has any visible effect apart
from honoring the buffering mode.
7.19.5.6 The setvbuf function
... If buf is not a null pointer, the array it points to may be used
instead of a buffer allocated by the setvbuf function and the argument
size specifies the size of the array; otherwise, size may determine
the size of a buffer allocated by the setvbuf function. ...
Note the use of "may" instead of "shall".
Andreas.
