Function overloading - 08/20/08 15:51
Hello,
in Lite-C (A7.10.1) function overloading does not work properly when the respective function takes a pointer as an argument (or so it seems; apparently there is a relation).
Here is the thread that led to this conlusion.
Example:
The following code works without any problems:
However, when a pointer is added to the overloaded function as a second argument, overloading doesn't work anymore.
In the following example the first function prototype is always used, leading to a crash. (typecast doesn't help)

int test(char* s, int *i) {
return ((int)str_to_num(s));

I actually run into the same
