Francois,
Take a look at the OBElementTable class. There is a global static
instantiation of it (named 'etab') available through the mol.h header,
see the example code on
http://openbabel.org/api/2.3/classOpenBabel_1_1OBElementTable.shtml.
The simple program:
#include <iostream>
#include <openbabel/mol.h>
int main(int, char **)
{
std::cout << "The mass of carbon is "
<< OpenBabel::etab.GetMass(6)
<< " amu." << std::endl;
return 0;
}
Compiled with
g++ -lopenbabel -I/usr/include/openbabel-2.0/ test.cpp
produces
$ ./a.out
The mass of carbon is 12.0107 amu.
HTH,
Dave
