What is _beginthread() function? : C

[Servant]

Hi, I am working in the MNC company from last week. In company, I working on the C programming language. I recently joined the company so, till now I don't know how they can work in the company. I have to complete the project that is they given by my executive, within week. So, I have to complete project using the coding that has Beginthread function. But I don't know about the Beginthread function. So, can anyone tell me about the Beginthread function.

In programming language like C, the beginthread function can be declared in the header file process.h. The beginthread function is a function that can creates a new thread of execution within the current process. A thread of execution means that from a fork of a computer program in more than two concurrently running tasks. The following is the Syntax of the beginthread function :
uintptr_t _beginthread(
void( *start_address )( void * ),
unsigned stack_size,
void *arglist
);

The following are the parameters of the beginthread function :
1. start_address : It starts the start address of a routine that begins execution of a new thread.
2. stack_size : It scan be used for stack size of a new thread or 0.
3. arglist : It can be used to pass Argument list to new thread or NULL.
4. security : It can be used to determines whether the returned handle can be inherited by child processes.
5. initflag : It can be used for to determine initial state of a new thread.
6. thrdaddr : It can be used for Pointing to a 32-bit variable that receives the thread identifier.

I think the begin thread function can be used to create the thread. The _beginthread function can be used to create a thread that can starts the execution of a routine at starting of the address. The __cdecl calling convention must be used for the routine at start_address and The _beginthread function can not have return value. The _beginthread function can be terminated automatically when the thread returns from that routine. The _beginthread can returns -1L on an error.

The following example helps you to know about the _beginthread() function :
#include <windows.h>
#include <process.h>
#include <stddef.h>
#include <stdlib.h>
#include <conio.h>
int main()
{
CHAR cr = 'B';
hStdO = GetStdHandle( STD_OUTPUT_HANDLE );
GetConsoleScreenBufferInfo( hStdO, &csbi );
_beginthread( ChkKey, 0, NULL );
while( repeat )
{
_beginthread( Bounce, 0, (void *) (cr++) );
Sleep( 2000L );
}
}
