I don't know of any reason why a C function couldn't return an array,
so the problem is probably in your code...
regards, tom lane
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.
