wide string literal cast to 'LPSTR'
Remarks
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.
Example
The following example generates C4905.
// C4905.cpp
// compile with: /W1
#pragma warning(default : 4905)
#include <windows.h>
#include <stdlib.h>
#include <stdio.h>
int main()
{
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);
return 0;
