How to identify when a function is being called using IDA?

Question

I'm debugging a .exe file on Windows with IDA's debugger.

How can I identify when the code calls the random() function?

Answer 1

While the debugger is loaded and the executable is running, double-click on the random() function entry in the imports tab/view to see it in the disassembler view. Then place a breakpoint on it using Debugger -> Breakpoints -> Add breakpoint.
