g.The CreateThread function creates another thread for the process. A carefully crafted thread must provide the starting address of the shared code to start a new thread. A process can have many threads performing the same function at the same time.
The CreateThread function generates a new thread for the approach. The creator of the thread must specify this starting code address where he should practice the new thread.

To create a thread that would work normally in the virtual address space of another process, go to CreateRemoteThread function.
Syntax
How do you create a thread in Windows?
The Windows API provides the CreateThread () function to create a contribution. Each thread has its own package (see Thread vs. Process). You can explain the heap size in bytes of the new thread using the stackSize parameter, which is the second argument to the CreateThread () function in the following example.
HANDLING CreateThread ( [in, optional] LPSECURITY_ATTRIBUTES lpThreadAttributes, [inch] SIZE_T dwStackSize, [in] LPTHREAD_START_ROUTINE lpStartAddress, [in, optional] __drv_aliasesMem LPVOID lpParameter, [in] DWORD dwCreationFlags, [out, optional] LPDWORD lpThreadId);
Parameters
Pointer to SECURITY_ATTRIBUTES A structure that depends on whether the descriptor returned by the inferior processes can be genetic. iflpThreadAttributes is NULL, normally the handle cannot be inherited.

The lpSecurityDescriptor member defines the part of the structure that is defined There is a security descriptor for working with a new thread. If lpThreadAttributes is NULL, the thread receives the default home security descriptor token from the creator.
Initial size, including stack, in bytes. The system moves this value to the next page. If this parameter is null, the location uses the default size for the exe. For more information see Thread stack size .
What is a Win32 thread?
Win32 streams are implemented in the kernel area of the Windows operating system. The CreateThread () function creates a thread if attributes are passed as parameters. Attributes are the size of the stack, the banner to provide the blocking status when the site starts up, the summarization function, and the assurance that these are parameters.
Hint on how to use the definition of the function that the stream should follow. This pointer represents the starting address of its stream. For more information on the stream function, see ThreadProc .
A suggested variable to pass to allow for the stream.
| value | Value |
|---|---|
|
The stream starts immediately after creation. |

The thread is put into a suspended state and will not run untilThe ResumeThread function is called. |

The dwStackSize parameter specifies the initial size of the parking space for your stack. If an indicator is specified here, dwStackSize does not indicate the waste amount. |
Pointer to a variable that will receive the thread ID. This is the parameter of leadershipNULL, no thread ID is returned.
Returned Value
If the function succeeds, a handle to the original stream is returned.
If the function fails, the return value must be NULL. Call for more detailed information about the error GetLastError .
Note that much of CreateThread can succeed even for reasons wherelpStartAddress to data, code, or not available. If the beginning of the addressnot valid if I said the thread is running, an exception is thrown and the thread exits normally. End of stream due to return toAn invalid start address is considered a failure of the thread process. This behavioral training is similar toasynchronously with mother nature itself CreateProcess , whereA process is created even if it references invalid or missingExisting dynamic links in your local library (DLL) number
The number of threads created by a process is limited by the available main memory. By default, each thread has one megabyte of stack. Hence, you will probably create a maximum of 2048 threads. If you moderate the default stack size, you can create more threads. However, your application will perform better if you create a specific thread for each processor and create request queues for which the application maintains specific contextual information. A thread processes multiple requests in one queue before processing requests for the next queue.
A new stream command is created with top access THREAD_ALL_ACCESS. If no security descriptor is used when creating a thread, a default security descriptor is created for the newly found thread using the primary token of the particular process that created its thread. When a caller tries to access a thread using OpenThread , the caller’s effective token is usually comparing It is combined with this security descriptor to allow or deny access.
The newly created string has full access rights to itself when calling the GetCurrentThread function.
Windows Server 2003: thread access to rights is determined by evaluating the primary token of all processes in which the thread was specially created against the standard security descriptor designed for the thread. If the is string was created in a remote process, the most important token of the remote process is used. Therefore, the newly created location may also have limited access rights when GetCurrentThread is called. Some privileges may be missing when adding THREAD_SET_THREAD_TOKEN and Thread_get_context, causing unexpected errors. It is not recommended to use as a trigger the creation of a chain, impersonating another person.
If the thread is found executable (c. / p>
How can we CreateThread?
You can customize threads by implementing an executable interface to override the run () method. Then you can create a thread object and call the new start () method.
The thread starts execution from the function specified by the lpStartAddress parameter. When a particular function returns, DWORD return detection is used to terminate the thread for an implicit call ExitThread . Use GetExitCodeThread to get the return value of the thread.
The stream was created with the conservative priority THREAD_PRIORITY_NORMAL. Use and SetThreadPriority in GetThreadPriority is used to determine and set the priority of a thread.
When a thread terminates, a particular thread object goes into a signaled state, in which all threads that were waiting on the object are undoubtedly waiting.
The stream of an object remains in the module until the stream is completed and all of its descriptors are closed, includes a call CloseHandle . functions,
End of process , guide ,Create a topic createremotethread and the route that starts (after the call from CreateProcess ) are serialized to each other within a process. Only one event associated with these events can occur in the home address space. This means that the following restrictions apply:
- As long as the process is starting and only DLL initialization routines are used, new threads can usually be created, but they will not start running until the DLL initialization for the process is will be completed.
- A separate thread in a process can be a DLL initialization or detach routine.
- ExitProcess will exit, but only after there are no more threads in the initialization or detach procedures of your DLL.
The thread in the executable that calls the C Runtime Library (CRT) should use _beginthreadex as good as, _endthreadex Flow control functions, notCreate a topic and Lead wire ; this requires the use of a multithreaded version of the CRT. When the stream was created withCreate a topic Conferencing with CRT, CRT can terminate the process in low memory conditions.
