Use of LINE as a macro parameter conflicts with standard C usage.

Charles Miller · ‎2020-07-29

Several macros in stm32f4xx_hal_exti.h use __LINE__ as a macro parameter. Example:

#define IS_EXTI_PENDING_EDGE(__LINE__) ((__LINE__) == EXTI_TRIGGER_RISING_FALLING)

__LINE__ is a reserved preprocessor symbol which expands to the integer line number of the file in which it is parsed. It should not be used as it is now. F4 HAL library v1.25 (and others).

Hi @Charles Miller ,

Even if it is with some delay, it remains relevant to report what you highlighted to our development team. This is what I did.

Thanks,
