Function stoul

support/StringSupport.h:91–114

Convert string values to unsigned long. * * @note This function implements the same behaviour as std::stoul. The latter * is missing in some Android toolchains. * * @param[in] str String to be converted to unsigned long. * @param[in] pos If idx is not a null pointer, the function sets the value of pos to the position of the first character in str after the number. * @param[in] base

 * @return Unsigned long representation of @p str.
