insert values

Hi,

I have the following type :
--------------------------------------------
CREATE FUNCTION entier_in(opaque)   RETURNS entier   AS '/ens/klimann/PostgreSQL/entier.o'   LANGUAGE 'c';

CREATE FUNCTION entier_out(opaque)   RETURNS opaque   AS '/ens/klimann/PostgreSQL/entier.o'   LANGUAGE 'c';

CREATE TYPE entier (   internallength = 8,   input = entier_in,   output = entier_out
);
--------------------------------------------

where entier.c is the following program :
--------------------------------------------
#include <stdio.h>

typedef struct entier {   long x;
} entier;


entier * entier_in(char *s)
{ entier *result;
 result = (entier *)malloc(sizeof(entier)); result->x = atoi(s);
 return (result);
}

char * entier_out(entier *n)
{ char *result; if (n == NULL)   return(NULL); result = (char *) malloc(60); sprintf(result, "%d", n->x);
 return(result);
}
----------------------------------------------

then I create the table entiers as follows :
----------------------------------------------
CREATE TABLE entiers (  val entier
);
----------------------------------------------

How can I insert a value in this table ?

I have tried several methods, but I can't find
a correct one.

Does someone have an idea ?


Thanks a lot,
Ines.
