警告C4244:'=':从'INT_PTR'转换为'HRESULT',可能会丢失数据 [英] warning C4244: '=' : conversion from 'INT_PTR' to 'HRESULT', possible loss of data
问题描述
HI,
请帮我解决警告。 VS2013,64BIT配置。为什么这样的警告
DllRegisterServer函数的重新类型是HRESULT。但为什么它在x64中显示出警告?

void somefunction(){

    FARPROC entryPt;
    entryPt = GetProcAddress(hDisplayLib,TEXT(" DllRegisterServer"));
    if(entryPt!= NULL)
    {
      HRESULT hResult;
      hResult =(* entryPt)();
      if(SUCCEEDED(hResult))
      {
      }¥b $ b     }
}
STDAPI DllRegisterServer(无效)
{
//
}

无效功能(){
$
     .....      FARPROC entryPt;       entryPt = GetProcAddress(hDisplayLib,TEXT(" DllRegisterServer"));
entryPt的类型必须与您指向的函数的实际原型相匹配至。在这种情况下,
HRESULT(STDAPICALLTYPE * entryPt)();
HI,
Please help me to solve the warnings. VS2013, 64BIT configuration. Why such warning
Retrun type of DllRegisterServer function is HRESULT. But why it is showing warings in x64?

HRESULT hResult;
hResult = (*entryPt)();
if (SUCCEEDED(hResult))
{
}
}
}
STDAPI DllRegisterServer(void)

void somefunction(){
..... FARPROC entryPt; entryPt = GetProcAddress(hDisplayLib, TEXT("DllRegisterServer"));The type of entryPt must match the actual prototype of the function you make it point to. In this case,
HRESULT (STDAPICALLTYPE* entryPt)();
