The result is temporary because any change to the CString contents invalidates old copies of the LPCTSTR pointer.It does make sense in some cases to provide a C-style string. For example, there can be a situation where a called function is written in C and doesn't support objects. In ...
InC++, If we want to pass arguments to functions we can either pass the actual value, apointerto the value, or a reference to the value. This concept becomes crucial when we want a function to modify the original variable. So, if we pass parameter to afunctioneither by pass by pointer...
This is achieved by you passing a pointer to your own state information - through (v)fctprintf() and all the way to your own out() function. "... but I don't like the underscore-suffix names :-(" You can configure the library to alias the standard library's names, in which case...

Notice that you must pass the Rect structure by reference, since the function expects a pointer to a RECT type.

a variable is passed to a function by reference, a pointer is assigned to the variable in question so that any changes to it within the function are applied globally. In this article, we’re going to learn how to pass primitive data to a function by reference. The next instalment will ...
