I wish did fix the issue. PROBLEM: , Vala 0.8.1 is your problem. Vala 0.16 produced code :
void method_1 (gint a, gint* b, gint* c) {
gint _vala_b = 0;
gint _tmp0_;
gint _tmp1_;
_tmp0_ = a;
_tmp1_ = *c;
_vala_b = _tmp0_ + _tmp1_;
*c = 3;
if (b) {
*b = _vala_b;
}
}

wish help you to fix your issue No, this is not possible. If you use an out parameter then you are not permitted to read the value before assigning to the variable, for the reason the compiler has already told you. If you use ref then the parameter must be initialized before it is allowed to be passed in.

it should still fix some issue I want that when user send @dispid null then it will check in where clause with DISPID = IS NULL and when user send any value then it will check with that value in below query. Here DISPID is int type and null allowed , Please try: code :
WHERE CANCELLED = 0 AND
((DISPID IS NULL and @DISPID IS NULL) OR DISPID=@DISPID)
