* @brief Calculate all the critical points for a given composition
* @param handle The integer handle for the state class stored in memory
* @param length The length of the buffers passed to this function
* @param T The pointer to the array of temperature (K)
* @param p The pointer to the array of pressure (Pa)
* @param rhomolar The pointer to the array of molar density (m^3/mol)
* @param stable The pointer to the array of boolean flags for whether the critical point is stable (1) or unstable (0)
* @param errcode The errorcode that is returned (0 = no error, !0 = error)
* @param message_buffer A buffer for the error code
* @param buffer_length The length of the buffer for the error code
* @return
*
* @note If there is an error in an update call for one of the inputs, no change in the output array will be made
