typedef void *TIMER_ID; TIMER_ID zcd_timer;void zcd_callback_func(void);int zcd_unit_sw_timer_create(zcd_callback_func, NULL, &zcd_timer);为什么报错

The code provided is incomplete and contains errors. Here is a corrected version:

typedef void (*TIMER_CALLBACK)(void);
typedef void* TIMER_ID;

TIMER_ID zcd_timer;

void zcd_callback_func(void) {
// implementation of the callback function
}

TIMER_ID zcd_unit_sw_timer_create(TIMER_CALLBACK callback_func, void* context, int interval_ms) {
// implementation of the timer creation function
// using the provided callback function, context and interval
// returns a timer ID
}

// Example usage:
zcd_timer = zcd_unit_sw_timer_create(zcd_callback_func, NULL, 1000); // creates a timer with a 1 second interval and no context data
