int      *const user_field   --- user_field values

This function returns the user field values for the given entity.


Specific Errors:
    PK_ERROR_no_user_fields        user_field option to PK_SESSION_start
                                   not set greater than zero.


The number of integers returned is that set by the user_field option of
PK_SESSION_start.  This number is available via PK_SESSION_ask_user_field_len.

If the user field values have not been explicitly set by
PK_ENTITY_set_user_field then they will all be returned as zero.
