OSGUTIL_EXPORT const char* osgUtilGetLibraryName | ( |  | ) |

| osgUtilGetLibraryName() returns the library name in human friendly form.

OSGUTIL_EXPORT const char* osgUtilGetVersion | ( |  | ) |

| osgUtilGetVersion() returns the library version number. Numbering convention : OpenSceneGraph-1.0 will return 1.0 from osgUtilGetVersion. This C function can be also used to check for the existence of the OpenSceneGraph library using autoconf and its m4 macro AC_CHECK_LIB. Here is the code to add to your configure.in:
     #
     # Check for the OpenSceneGraph (OSG) utility library
     #
     AC_CHECK_LIB(osg, osgUtilGetVersion, ,
        [AC_MSG_ERROR(OpenSceneGraph utility library not found. See http://www.openscenegraph.org)],)
