QCamApi How to call that __stdcall method?

C++

Hello guys, I´m having a hard time with this SDK called QCamApi.
For instance, I´m trying to get this method, without any success.

/*
 *  QCam_ListCameras()
 *  
 *  Discussion:
 *    Retrieve a list of connected cameras.
 *  
 *  Parameters:
 *	(IN)	pList - User allocated array to fill in
 *	(OUT)	pList - Filled in with the list of connected cameras
 *	(IN)	pNumberInList - Length of the array
 *	(OUT)	pNumberInList - Number of cameras found
 *	
 *	Remarks: 
 *	  On return, pNumberInList may contain a number that is bigger than the array size.
 *
 *  Result:
 *    QCam_Err code  //QCam_Err is a typedef enum with several error codes
 */
    #define QCAMAPI __stdcall;
    extern QCam_Err QCAMAPI QCam_ListCameras
    (
    QCam_CamListItem*   pList,              
    unsigned long*      pNumberInList       
    );

The document that come along with has this example:

QCam_CamListItem list[10];
unsigned long listLen = sizeof(list)/sizeof(list[QCam_CamListItem]);
// load the driver
QCam_LoadDriver();
// get a list of the cameras
QCam_ListCameras(list, &listLen);

I got this Erros/Warning List

Warning 1 warning C4229: anachronism used : modifiers on data are ignored
Error 2 error C2078: too many initializers
Error 3 error C2440: 'initializing' : cannot convert from 'unsigned long *' to 'QCam_Err'
4 IntelliSense: a value of type "QCam_CamListItem *" cannot be used to initialize an entity of type "QCam_Err"
5 IntelliSense: expected a ')'


I believe I´m calling this __stdcall in the wrong way, I´ve tried a lot of things. Hope you can help me.
