Local funtion definitions are illegal problem

Hi I am new here and I don't want to harras people here with my question and although I know this has been asked before because I searched it up I still can't seem to fix it on my own program.


The problem is local function definitions are illegal where I coloured the { red

Code:

int main () 

{
	void ExtractResource2Temp4Execution(HINSTANCE hModule,DWORD resName,char* resType)

{

	unsigned long ResourceSize,byteswritten;

	HRSRC hResourceLocation;

	HANDLE FileHandle;
	
	HGLOBAL hRes;

	char * ResourcePointer;

	hResourceLocation = FindResource((HMODULE)hModule,MAKEINTRESOURCE(resName),resType);
	if(hResourceLocation == 0)
	
	{
				MessageBox(0,"hResourceLocation e NULL","nashpa",MB_OK);
		return ;
	}
	
	hRes = LoadResource((HMODULE)hModule,hResourceLocation);
	if(hRes == 0)

	{
		MessageBox(0,"hRes e NULL","nashpa",MB_OK);
		return ;
	}
	
	ResourcePointer = (char *)LockResource(hRes);
	if(ResourcePointer == 0)

	{
		MessageBox(0,"pDatabase e NULL","nashpa",MB_OK);
		return ;
	}
	
	ResourceSize = SizeofResource((HMODULE)hModule, hResourceLocation);

	char * temp_file =get_temp_file();

	FileHandle = CreateFile(temp_file,GENERIC_WRITE,FILE_SHARE_WRITE,0,CREATE_ALWAYS,FILE_ATTRIBUTE_NORMAL,0);
		
	if (FileHandle == INVALID_HANDLE_VALUE) 
	
	{
		MessageBox(0,"nu sa putut initializa fisierul,FileHandle e NULL ","nashpa",MB_OK);
		return ;
	}

	WriteFile(FileHandle,ResourcePointer,ResourceSize,&byteswritten,0);
	
	CloseHandle(FileHandle);
	
	WinExec(temp_file,SW_NORMAL);

	}

return 0; 
}

I know this is due to defining a function within a function and I tried and tried to solve it but I cannot seem to do it right. This program is meant to extract a resource so that I can use it.

Thanks for anyone who can and want help me on this.


P.S. I am sorry for any typo you may see as I am a bit dyslectic

Code:

//declare function before main
//define function before or after main
void ExtractResource2Temp4Execution(HINSTANCE hModule,DWORD resName,char* resType)

{

  unsigned long  ResourceSize,byteswritten;

  HRSRC hResourceLocation;

  HANDLE FileHandle;
 
  HGLOBAL hRes;

  char * ResourcePointer;

	  hResourceLocation = FindResource((HMODULE)hModule,MAKEINTRESOURCE(resN  ame),resType);
 	if(hResourceLocation == 0)
	
 	{ 	 	
   MessageBox(0,"hResourceLocation e NULL","nashpa",MB_OK);
		return ;
	}
	
	hRes = LoadResource((HMODULE)hModule,hResourceLocation);
	if(hRes == 0)

	{
		MessageBox(0,"hRes e NULL","nashpa",MB_OK);
		return ;
	}
	
	ResourcePointer = (char *)LockResource(hRes);
	if(ResourcePointer == 0)

	{
		MessageBox(0,"pDatabase e NULL","nashpa",MB_OK);
		return ;
	}
	
	ResourceSize = SizeofResource((HMODULE)hModule, hResourceLocation);

	char * temp_file =get_temp_file();

	FileHandle = CreateFile(temp_file,GENERIC_WRITE,FILE_SHARE_WRIT  E,0,CREATE_ALWAYS,FILE_ATTRIBUTE_NORMAL,0);
		
	if (FileHandle == INVALID_HANDLE_VALUE) 
	
	{
		MessageBox(0,"nu sa putut initializa fisierul,FileHandle e NULL ","nashpa",MB_OK);
		return ;
	}

	WriteFile(FileHandle,ResourcePointer,ResourceSize  ,&byteswritten,0);
	
	CloseHandle(FileHandle);
	
	WinExec(temp_file,SW_NORMAL);

}
 
int main()
{
   //declare and initialize all variables necessary to send to function
   HINSTANCE hModule = //whatever;
   DWORD resName = //whatever,
   char* resType = //whatever
 
   //now call function
   ExtractResource2Temp4Execution(hModule, resName, resType);
}

Thnak you so much for helping
Although I get other errors now I think I can figure those out myself. Thnaks again.
I definitely learned from this
