The function has been entered, and the first line is about to be executed. The first executable code after the prolog is used as the actual breakpoint location. This may be a line where a local variable is being initialized. In the case of C++ constructors, execution stops after all base class constructors have executed. If the -instr modifier is used (see -instr), it is the first instruction of the function about to be executed. The function specification can take a formal parameter signature to help with overloaded function names or template instance specification. For example:
stop in mumble(int, float, struct Node *)
Do not confuse in function with the-in function modifier.
