在Xcode

Question

沒有匹配函數調用 '在pthread_create' 不匹配函數調用 '在pthread_create'

# include <stdio.h> 
# include <pthread.h> 

string nextProduced; 
string nextConsumed; 
char *BUFFER; 
int BufferSize = 10; 
void putItemIntoBuffer(); 
string produceItem(); 
string consumeItem(); 
void *Producer(); 
void *Consumer(); 

pthread_cond_t Buffer_Not_Full=PTHREAD_COND_INITIALIZER; 
pthread_cond_t Buffer_Not_Empty=PTHREAD_COND_INITIALIZER; 
pthread_mutex_t mVar=PTHREAD_MUTEX_INITIALIZER; 

int main() 
{ 
pthread_t pro, con; 

BUFFER=(char *) malloc(sizeof(char) * BufferSize); 

pthread_create(&pro,NULL,Producer,NULL);// Creates threads 

pthread_create(&con,NULL,Consumer,NULL);// Creates threads 

pthread_join(pro,NULL); 

pthread_join(con,NULL); 


return 0; 

}

Xcode中給我的錯誤， 「找不到匹配函數調用 '在pthread_create'」。我不知道我做錯了什麼。任何幫助將不勝感激。

我能夠得到它編譯，但我現在得到這個消息。 我不知道問題是什麼。 線程1，隊列：com.apple.main線程

你的生產者和消費者功能的簽名應該如下：

void *Producer(void *data); 
void *Consumer(void *data); 

我相信你需要通過屬性參數以及。一個很好的例子見Apple's Documentation。
