wide string literal cast to 'LPSTR'
The compiler detected an unsafe cast. The cast did succeed, but you should use a conversion routine.
This warning is off by default. See Compiler Warnings That Are Off by Default for more information.
The following sample generates C4905.
// C4905.cpp// compile with: /W1 #pragma warning(default : 4905) #include<windows.h> #include<stdlib.h> #include<stdio.h>intmain() { LPSTR y = (LPSTR)L"1234"; // C4905// try the following lines instead// wchar_t y[128];// size_t sizeOfConverted;// errcode err = 0;//// err = mbstowcs_s(&sizeOfConverted, &y[0], 128, "12345", 4);// if (err != 0)// {// printf_s("mbstowcs_s failed!");// exit (-1);// }// wprintf(L"%s\n", y);return0; }
