Based on the name of the function, I think the OP just needs
an integer-to-string conversion.
Two steps:
1. See http://www.parashift.com/c++-faq-lit....html#faq-39.1
to see how to convert an int to a std::string (the FAQ is for doubles,
but
you can adapt it easily to int, and I see no need for the exception
stuff
in that case).
2. textout_ex(std_string_from_step_1.c_str());
