Actually, I don't think there are any.

C99 7.5p3:

    The value of errno is zero at program startup, but is never set
    to zero by any library function.  The value of errno may be set
    to nonzero by a library function call whether or not there is
    an error, provided the use of errno is not documented in the
    description of the function in this International Standard.
