try { // Some code that may throw an exception } catch (const std::exception& e) { std::string errorMessage = "Error: " + std::string(e.what()); SetErrorString(errorMessage.c_str()); }
void myFunction() { if (/*some error occurred*/) { SetErrorString("Error: Something went wrong."); return; } // Other code }In this example, we have a custom function that checks for an error condition. If the error is detected, we set a custom error message using SetErrorString. This code also uses the C++ Standard Library. In conclusion, SetErrorString is a function in the C++ Standard Library that helps programmers to identify the cause of errors in their code. It is not a part of any external package library.
