is_master_ def:
volatile bool is_master_;
另一个线程将is_master _ 值设置为true,但似乎 is_master _ 值dosnt flush(它没有发生致命错误已发生...) 。如果我添加cout<< “foo”<
void MasterSlaveSynchronize::validateSingleMaster(){
if(is_master_){
cout << "FATAL ERROR HAS OCCURRED BOTH MASTER";
if(!is_leader_master_){
cout << "CHOSE AS VICTIM IN MASTER-MATSER. SET THIS HOST AS SLAVE";
is_master_ = false;
}
}
}
来电者代码:
while(1){
int n = recvfrom(sockId, buf, HEARBEAT_SIZE, 0, (struct sockaddr *) &from,
&length);
if (n < 0) {
REGISTER_ERROR("Failed to recieved hearbeat");
} else {
gettimeofday(&instance_->last_hearbeat_got_, NULL);
instance_->validateSingleMaster();
}
}

您希望我发表评论作为答案:
可能确实如此,但是因为你没有使用换行符输出流 没有冲洗。
这种行为在这里得到了相当好的解释:
Why does printf not flush after the call unless a newline is in the format string?
