FUNCTION TYPES
|
|
|
86 |
|
|
|
87 |
The various kinds of functions are given by combinations of the
|
|
|
88 |
following values, which are stored in the ellipsis field of the
|
|
|
89 |
corresponding function type. In C++ the only possibilities are
|
|
|
90 |
FUNC_NONE and FUNC_ELLIPSIS indicating whether or not the function
|
|
|
91 |
is declared with ellipsis; the fact that these have the values 0 and
|
|
|
92 |
1 is used. In C non-prototype functions introduce other kinds of
|
|
|
93 |
function:
|
|
|
94 |
|
|
|
95 |
FUNC_NO_PARAMS no type information,
|
|
|
96 |
FUNC_WEAK_PARAMS weak prototype or non-prototype definition,
|
|
|
97 |
FUNC_WEAK_ARGS implicit weak prototype.
|
|
|
98 |
|
|
|
99 |
During type construction the following values are used:
|
|
|
100 |
|
|
|
101 |
FUNC_NO_PARAMS no type information,
|
|
|
102 |
FUNC_PARAMS non-prototype definition,
|
|
|
103 |
FUNC_WEAK weak prototype.
