The following code

 DWORD WINAPI 
GetFileNameThread (PVOID lpParameter) 
{
PNM_INFO NmInfo=lpParameter; 
IO_STATUS_BLOCK IoStatus; 

NtQueryInformationFile (NmInfo - & gt; HFile, & amp; IoStatus, & amp; NmInfo - & gt; Info, 
Sizeof (NM_INFO) - sizeof (HANDLE), FileNameInformation); 

return 0; 
} 

EXTERN_C void GetFileName (HANDLE hFile, PCHAR TheName) 
{
HANDLE hThread; 
PNM_INFO Info=HeapAlloc (hHeap, 0, sizeof (NM_INFO)); 

The Info - & gt; HFile=hFile; 

HThread=CreateThread (NULL, 0, GetFileNameThread, Info, 0, NULL); 

If (MsgWaitForMultipleObjects (1, & amp; HThread, 
FALSE, INFINITE, QS_ALLINPUT)==WAIT_OBJECT_0)//the problem here 
{
The TerminateThread (hThread, 0); 
} 
The CloseHandle (hThread); 



Memset (TheName, 0, MAX_PATH); 

WideCharToMultiByte (CP_ACP, 0, Info - & gt; The Info. The FileName, Info - & gt; Info. FileNameLength & gt;> 1, TheName, MAX_PATH, NULL, NULL); 

HeapFree (hHeap, 0, Info); 
} 

The process and thread creation, the first 100 threads are no problem, but then when the waitforsingleobject child thread collapses, the main thread deadlock, beg to solve!

After the deadlock is like this

CodePudding user response:

Every time is open to a problem with the 117th threads

CodePudding user response:

0 xc000013a failed to create a thread?

CodePudding user response:

Ah, this is a deadlock or creating failed, why the main thread to exit if create failure? By adjusting and I found that seems to have been the cause of the induction of this phenomenon is the same file handle

CodePudding user response:

This is stuck

CodePudding user response:

"The same file handle
"The log file!

CodePudding user response:

Specific what to do, I am a little white, the great god to solve

CodePudding user response:

There is also a doubt is: the same handle, the handle work in named pipe, I create a thread is in order to get the pipe, the program's name piped goes like this:

But in front of the named pipe:

This can be, but just the named pipe not line, can also lead to the thread exits, why is this?

CodePudding user response:

Using a thread pool,

CodePudding user response:

Haven't solve ohoo...

CodePudding user response:

A named pipe is blocked waiting state enumeration so your code to handle to a named pipe will die lock away, and thread not threads do not have what relation,
GetFileInformationByHandleEx can't use? Want to write?
