I wrote a program that uses multiple threads to obtain some data, and then stores it in an array. Then when I close the console program, an event will be triggered, and then I will write the data in the array to a file in this event. .
But when I run this program for less than 10 minutes, writing files is normal. When I close the program for more than 20 minutes, it will only output some files and then the program will close itself.
The following is the code involving these places:
This is the call to SetConsoleCtrlHandler in the main function
int main(char*argv[], int argc)
{
//当你关闭的时候做一些处理工作
SetConsoleCtrlHandler(ConsoleHandler, TRUE);//接受控制台消息,做一些清理工作
//其他工作
}
This is the specific function implementation
BOOL WINAPI ConsoleHandler(DWORD msgType)
{
Print("I'm closing\n");
if (msgType == CTRL_C_EVENT ||msgType == CTRL_CLOSE_EVENT)
{
if (g_hTDF)
{
WriteResult(str);//这里就是我把数组中的内容写入文件的程序
Print("console Close complete!\n");
system("pause");
return TRUE;
}
return TRUE;
}
Has anyone encountered this problem?
Is this related to the buffer or something? Because intuitively, it may be that more data is received as time goes by.

CTRL_CLOSE_EVENT has a timeout mechanism, so no matter how long it takes to write data, the program will shut down after 5 seconds.
You can use CTRL_C_EVENT instead.
