Posted on October 14, 2015 at 23:23It's part of a different, older library, the SPL (Standard Peripheral Library), so download that one if you want to see its helpfile.
But it does not anything else than masking out individual bits from the status register, TIMx_SR, (if the respective interrupt has been enabled in TIMx_DIER):
/**
* @brief Checks whether the TIM interrupt has occurred or not.
* @param TIMx: where x can be 1 to 14 to select the TIM peripheral.
* @param TIM_IT: specifies the TIM interrupt source to check.
* This parameter can be one of the following values:
* @arg TIM_IT_Update: TIM update Interrupt source
* @arg TIM_IT_CC1: TIM Capture Compare 1 Interrupt source
* @arg TIM_IT_CC2: TIM Capture Compare 2 Interrupt source
* @arg TIM_IT_CC3: TIM Capture Compare 3 Interrupt source
* @arg TIM_IT_CC4: TIM Capture Compare 4 Interrupt source
* @arg TIM_IT_COM: TIM Commutation Interrupt source
* @arg TIM_IT_Trigger: TIM Trigger Interrupt source
* @arg TIM_IT_Break: TIM Break Interrupt source
*
* @note TIM6 and TIM7 can generate only an update interrupt.
* @note TIM_IT_COM and TIM_IT_Break are used only with TIM1 and TIM8.
*
* @retval The new state of the TIM_IT(SET or RESET).

Its Cube counterpart is presumably __HAL_TIM_GET_FLAG() (but without the DIER-checking part):
#define __HAL_TIM_GET_FLAG(__HANDLE__, __FLAG__) (((__HANDLE__)->Instance->SR &(__FLAG__)) == (__FLAG__))
I don't use Cube nor SPL.
