I tried to use atol but i get always 0 as result. Is this because I use a
binary cursor to select the data (there are some PostGIS datatypes inside my
resultset which are binary data).

Best regards,

Uh ... there is nothing at all locale-sensitive about atol, nor strtoul
which is what you really want to use for an OID.
