    _vsnprintf questions

    Hi all ,

    Are there any restrictions on the buffer size when using the above function?

    My debugger screams when the size is bigger then 6648

    anyone ?

    Thanks

    So long as you don't lie about the size.

    Perhaps you trashed memory somewhere else, and here is where you get to notice that there has been some past mistake..

    what compiler are you using and what is the error message? Also post the function that is calling _vsnprintf .
