This function applies the default type resolution rules
for the provided ufunc.

Returns 0 on success, -1 on error.

Validates that the input operands can be cast to
the input types, and the output types can be cast to
the output operands where provided.

Returns 0 on success, -1 (with exception raised) on validation failure.
