I have a problem with compiling C function in UDF. It seems that Flueent does not accept C functions. For instance, a short code:

DEFINE_ON_DEMAND
{
...
int imin(int, int); // line 1
...
int imin(int n, int m) // line 2
{
...
}
}

So, Fluent doesn't accept the function definition (line 2): "syntax error: missing ';' before '(' ". So, it treats the definition as a variable declaration. Remove "int" befor "init", it yields next problems, untill you remove the whole function definition.

What is the difference in the function syntax in pure C and the UDF?
