sprintf("Hi %1$s. Your name is %1$s", $name); This will nuke you at **runtime**, because of `$s` thing being handled as variable. If you got no $s for substitution, notice will be thrown. The solution is to use single quotes to prevent variable substitution in string: sprintf...
Thankfully, the buffer overflow is easy to spot in the Visual Studio debugger, though you will need to display the Memory window, and enter the address of the buffer to see it. In case you’ve missed it, the memory window is accessible during any debugging session by pressing ALT-6 (th...
sizeof tells you nothing about how many print characters an argument will consume in the output string.What you can do in your wrapper is use vsnprintf with the first two arguments being NULL and 0. The return value will tell you how large the output string needs to be. After you have...
For a, A, e, E, f, F, g, and G conversions, the result will always contain a decimal point, even if no digits follow it (normally, a decimal point appears in the results of those conversions only if a digit follows). For g and G conversions, trailing zeros are not removed from...
