// ABSL_PRETTY_FUNCTION |
|
// |
|
// In C++11, __func__ gives the undecorated name of the current function. That |
|
// is, "main", not "int main()". Various compilers give extra macros to get the |
|
// decorated function name, including return type and arguments, to |
|
// differentiate between overload sets. ABSL_PRETTY_FUNCTION is a portable |
|
// version of these macros which forwards to the correct macro on each compiler. |
