Function ParseStringFlag

rtpose_wrapper/src/gtest/gtest-all.cpp:5935–5945

Parses a string for a string 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 ParseStringFlag(const char* str, const char* flag, String* 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 == NULL) return false;

  // Sets *value to the value of the flag.
  *value = value_str;
  return true;
}

// Determines whether a string has a prefix that Google Test uses for its
// flags, i.e., starts with GTEST_FLAG_PREFIX_ or GTEST_FLAG_PREFIX_DASH_.
