[svn-r7104] Purpose:

    Bug fix

Description:
    Missing returning error for failures occur in C++ examples.

Solution:
    Added "return -1;" when an exception is caught.
    Also, turned off automatic error printing so that the C++ API
        will catch and handle the failures.

Platforms:
    SunOS 5.7 (arabica)
    Linux 2.4 (eirene)
    IRIX 6.5.11 (modi4)
