How to extract a whitespace from a stringstream c++

So I have a ASCII file that is supposed to begin with 2 characters a 'P' and a '2' nothing preceding and some form of white space after.

The trouble I'm having is testing an error case where there is white space preceding, I'm using a stringstream since the rest of the task requires similar operations and the rest works fine.

The issue I'm having is extracting white that leads, I know by default the extraction operator has the skipws flag set, so I tried turning the noskipws flag on with no success.

Here are a few things I've tried.

The file is ASCII and begins as such

// Imagine there is a space before the P
function(stringstream *pstream) {
    char test;
    (*pstream).get(test); //This will put the character P in test
    (*pstream) >> noskipws >> test; //This does the same thing
}

Simple question really how do I not ignore the whitespace while extracting using stringstream preferably since there is more i have to do with stream.

Figured it out the stream originally started as an ifstream, and didn't use the noskipws function so once I set it there, before converting it to a stringstream everything worked.
