 I want a function, chich output value is an array, and when I create
the
 function, it is defined as follows:

 create function path_inte(path,path) returns _point
 as '/net/ipfy/angel/postgres/geometry/libMWgeom.so' language 'c';

 When the function is used, the resultat is always: "{}", so I do not
 Know if:
-the function is not well defined, or
-the output value can not be an array


I have received your response about how a function, which output value
is an array, can be created (e-mail 10.04.99), but I get always the same

resultat. Would you be so kind as to write an example of a function,
which output value is an array ?

Thank you very much.
