[Mono-list] Problem with Oracle and Mono Charset...

[Hubert FONGARNAND]

I'm interested in implement connection pooling on oracle...
I just need some info about creating dllimport functions....

The C function is :
	OCIOCIConnectionPoolCreate((OCIEnv *)envhp,
                   (OCIError *)errhp, (OCICPool *)poolhp,
                   &poolName, &poolNameLen,
                   (text *)database,strlen(database),
                   (ub4) conMin, (ub4) conMax, (ub4) conIncr,
                   (text *)pooluser,strlen(pooluser),
                   (text *)poolpasswd,strlen(poolpasswd),
                   OCI_DEFAULT));

i've began :

			//fongarnand
			[DllImport ("oci")]
			internal static extern int OCIConnectionPoolCreate(IntPtr envhp,
				IntPtr errhp, IntPtr poolhp, ...

But i don't know wich datatype to use...		=09
