void setSemaphore(QSemaphore& sem) { semaphore = sem; } private: QSemaphore semaphore; };为什么报错

*s, int value) {
s->release(value);
}

This function takes a pointer to a QSemaphore object and an integer value as parameters. It then sets the value of the semaphore to the specified value by calling the QSemaphore method 'release'. The 'release' method increases the value of the semaphore by the specified amount, allowing threads to acquire the semaphore.
