DESCRIPTION
Function compares two views by analyzing the view type and their contents. Compare is based on following principles:
- The names are compared as strings and if they differ, result is returned.
- The count indicators (if used) are matched. If differ, result is returned.
- Only used fields are compared. Array values beyond count indicator (if used) are ignored.
- For CARRAY if length indicator is used, then it is matched in first place, if differ, result is returned.
- Null fields according to view file are equal.
All function arguments must not be NULL. In case of error (for example view is not defined), value -2 is returned.
RETURN VALUE
On success, Bvcmp() return -1 if view1/cstruct1 is lesser than view2/cstruct2. 0 is returned in case of both structures matches. 1 is returned in case if view1/cstruct1 is lesser greater than view2/cstruct2.
