Example
The following code outputs the string "New variable: abc3", followed by
"A real number: 1.3, an integer: 5" on the next line.
XPRBprob prob;
XPRBvar x1;
double a=1.3;
int i=5;
...
x1 = XPRBnewvar(prob, XPRB_UI, "abc3", 1, 100);
XPRBprintf(prob, "New variable: %s\n", XPRBgetvarname(x1));
XPRBprintf(prob, "A real number: %g, an integer: %d", a, i);
Further information
This function prints out text, data etc. from the user's program. It behaves like the C function
printf with the additional feature that whenever the printing callback
XPRBdefcbmsg is defined, this callback is executed instead of printing to the standard output channel.
