    Question printf-like function ?

    Hi folks,

    New to C, quick question about string manipulation.
    I need a highly efficient function to replace parameters in a string, basically the same way that printf works.

    char *template = "foo %s bar %s ...";
    newString = replaceParams(template, "param1", "param2");

    Is it possible to just redirect printf ? (as long as printf is efficient)
    Otherwise whats my best option (algorithm)?

    Thx

    Maybe strcpy and sprintf is what you are looking for. google them. To be honest I didn't really understand you
    Code - functions and small libraries I use


    It’s 2014 and I still use printf() for debugging.
