c++ - const void*

Guys,

I have a buffer buf. It's defined as const void* buf (In the param of a
function).

BOOL Write(const void* buf, ULONG nBytes, ULONG* pBytesWritten = NULL)
{

}

How can I access this variable data.

Is it by capturing it in const char* or something else.

Depends on whether you are coding C or C++


 BOOL Write(const void* buf, ULONG nBytes, ULONG* pBytesWritten = NULL)
 {

const char *ptr = ( const char * ) buf; // Should work for C and C++ const char *ptr = static_cast < const char * > ( buf ); // Should work for C++
 }
