The job might not be as hard as canonical sprintf() if GDAL is only 
using a subset of the possible features (e.g., printing only strings, 
chars, ints and floats).

Another way is to use printf/sprintf only for strings, and make your own 
printing routines that return strings. This complicates the call syntax 
but can be implemented easier. e.g.:

char* printnum(int n, char* psz)
{
    // go through digits of n and place into psz.
}

void foo(int n)
{
    char sz[30];
    sprintf(pszMsg, "Answer is: %s", printnum(n, sz));
}
