Function C and INOUT parameters

[diegoM]

Hello,

I have created a function in Postgres. His code is :

CREATE OR REPLACE FUNCTION add_one(INOUT arg1 integer, INOUT arg2 integer)
 RETURNS record
AS '$libdir/myDLL.dll', 'add_one'
LANGUAGE 'c' VOLATILE STRICT ;

In the DLL, I have a function C (it's just a test function) :

void add_one(int arg1, int arg2)
{
arg1 = arg1 + 1 ;
arg2 = arg2 + 1 ;
}

When I try to execute my function (select * from add_one(5, 10)), the server crashes (I must restart it). The problem is that if I use a function with one INOUT parameter, everything is OK. I think the problem is related to "RETURNS record", but I have no idea to solve it.

Any idea ?
Thanks

PS : For information, I work with PostgreSQL 8.3.6 and Visual Studio 2008 Professional Edition.
