Hello friends :
I get errors in the build file after creating the executable from the IDE.
These errors are all similar and in the same program segment, the error is as follows

F:\Disco\hmgdemo\Gestion\TFWIN\NG\9.07\Rs232.Prg: In function 'HB_FUN_OPENCOM':
F:\Disco\hmgdemo\Gestion\TFWIN\NG\9.07\Rs232.Prg:213:11: warning: format '%d' expects argument of type 'int', but argument 2 has type 'DWORD {aka long unsigned int}' [-Wformat=]
printf("Error %d\n",dwError);
^
F:\Disco\hmgdemo\Gestion\TFWIN\NG\9.07\Rs232.Prg:216:11: warning: passing argument 1 of 'hb_retnl' makes integer from pointer without a cast [-Wint-conversion]
hb_retnl( handle );

El segmento de programa es el siguiente :

The program segment is as follows:

#pragma BEGINDUMP

#define BUFF_OUT 1024
#define GENERIC_READ 0x80000000
#define GENERIC_WRITE 0x40000000

#include <windows.h>
#include <winbase.h>
#include <hbapi.h>

HB_FUNC( OPENCOM )
{
HANDLE handle ;
DWORD dwError;

//handle = CreateFile(hb_parc( 1 ),( GENERIC_READ | GENERIC_WRITE ), 0, 0, OPEN_EXISTING, FILE_ATTRIBUTE_NORMAL, 0);

handle = CreateFile(hb_parc( 1 ),( GENERIC_READ | GENERIC_WRITE ), 0, NULL, OPEN_EXISTING, 0, NULL);

if(handle == INVALID_HANDLE_VALUE)
{
dwError = GetLastError(); *** Estas lineas se hace referencia
printf("Error Createfile \n");
printf("Error %d\n",dwError);
}

hb_retnl( handle );
}

Alguien sabe como podre solucionarlo

Saludos cordiales

Does anyone know how I can solve it

Hi Mario,
the "errors" you get are actually warnings raised by C-compiler.
the problem is that the function you posted needs some cleanup,
since it's contains unnecessary/useless lines of code.
Try to replace it with the code below and see if helps:

Code: Select all

HB_FUNC( OPENCOM )
{
	HANDLE handle ;
	handle = CreateFile(hb_parc( 1 ),( GENERIC_READ | GENERIC_WRITE ), 0, NULL, OPEN_EXISTING, 0, NULL);
	hb_retnl( (long)handle );
}

regards,
Pete
