Hello,
I posted my problem (on pgsql-interfaces list) about the INOUT parameters on
PostgreSQL 8.3.6 (Win32), but without success. I re-post my question here,
while hoping to have more success.
When I use a function with one INOUT (or OUT) parameter like below, everyting
is OK.
CREATE OR REPLACE FUNCTION add_one(INOUT arg integer)
RETURNS integer AS '$libdir/myDLL.dll', 'add_one'
LANGUAGE 'c' VOLATILE STRICT ;
// In 'myDLL'
void add_one(int arg)
{
arg = arg + 1 ;
}
select * from add_one(10) ; // OK
But when I use 2 or more INOUT (or OUT) parameters like below, the server
crashes with exception 0xC0000005 (access violation).
CREATE OR REPLACE FUNCTION add_one(INOUT arg1 integer, INOUT arg2 integer)
RETURNS record AS '$libdir/myDLL.dll', 'add_one'
LANGUAGE 'c' VOLATILE STRICT ;
void add_one(int arg1, int arg2)
{
arg1 = arg1 + 1 ;
arg2 = arg2 + 1 ;
}
select * from add_one(10, 20); // CRASH
I probably understood something wrong with the INOUT parameter. Is there
someone to help me ? Thanks.
