I see. Something like this?
```cpp
ModuleSP main_module_sp = target_sp->GetExecutableModule();
FileSpecList shared_lib_filter;
shared_lib_filter.Append(main_module_sp->GetFileSpec());
BreakpointSP bp_sp = target_sp->CreateBreakpoint(
&shared_lib_filter, nullptr, "main", eFunctionNameTypeFull,
eLanguageTypeUnknown,
0, eLazyBoolNo, false, false);
```
