Function ParseInt32Flag

tests/gtest/gtest-all.cc:7216–7226

Parses a string for an Int32 flag, in the form of "--flag=value". On success, stores the value of the flag in *value, and returns true. On failure, returns false without changing *value.

// On success, stores the value of the flag in *value, and returns
// true.  On failure, returns false without changing *value.
bool ParseInt32Flag(const char* str, const char* flag, Int32* value) {
  // Gets the value of the flag as a string.
  const char* const value_str = ParseFlagValue(str, flag, false);

  // Aborts if the parsing failed.
  if (value_str == nullptr) return false;

  // Sets *value to the value of the flag.
  return ParseInt32(Message() << "The value of flag --" << flag,
                    value_str, value);
}

// Parses a string for a string flag, in the form of
