function prototype

HANDLE CallWindowsApiFunc(
    LPWINAPISTRUCT lpWinApiStruct,          // pointer to a WINAPI struct
    LPWORD lpResult                         // pointer to a DWORD that will receive the error code
)


 structures

typedef struct _WINAPI {
    BYTE cBytes;                            // length jf the structure, in bytes
    BOOL bSearchSystemPath;                 // search system path for library, application directory only if false
    WORD Reserved1;                         // reserved, must be zero
    WORD Reserved2;                         // reserved, must be zero
    CHAR szFuncName[WA_MAXFUNCNAME];        // name of the function to retrieve
    CHAR szLibName[WA_MAXLIBNAME];          // name of the library
} WINAPI, *LPWINAPI;


 defines

#define WA_MAXFUNCNAME 255
#define WA_MAXLIBNAME  255


 notes

If the function succeeds, the return value specifies a function handle.

If the function fails, the return value is HFUNC_ERROR. To get extended 
error information, call GetLastError.  Additional error information can 
be retrieved from the lpResult parameter



 usage example:

WINAPI WinApi;
HANDLE hFuncHandle;
DWORD dwResult;

WinApi.cBytes = sizeof(WINAPI);
WinApi.szFuncName = "OpenFile";
WinApi.szLibName = "kernel32.dll";
WinApi.bSearchSystemPath = TRUE;

hFuncHandle = CallWindowsApiFunc(&WinApi, &dwResult);
