QuestionConvert function to read from string instead of file in C Pin

I've been tasked with updating a function which currently reads in a configuration file from disk and populates a structure:

static int LoadFromFile(FILE *Stream, ConfigStructure *cs)
{
  int tempInt;

   ...

  if ( fscanf( Stream, "Version: %d\n",&tempInt) != 1 )
  {
    printf("Unable to read version number\n");
    return 0;
  }
  cs->Version = tempInt;
   ...

}

to one which allows us to bypass writing the configuration to disk and instead pass it directly in memory, roughly equivalent to this:
static int LoadFromString(char *Stream, ConfigStructure *cs)

A couple of things to note:

• The current LoadFromFile function is incredibly dense and complex, reading dozens of versions of the config file in a backward-compatible manner, which makes duplication of the overall logic quite a pain.
• The functions that generate the config file and those that read it originate in totally different parts of the old system and therefore don't share any data structures so I can't pass those directly. I could potentially write a wrapper, but again, it would need to handle any structure passed in a backward-compatible manner.
• I'm tempted to just pass the file as is in as a string (as in the prototype above) and convert all the fscanf's to sscanf's but then I have to handle incrementing the pointer along (and potentially dealing with buffer overrun errors) manually.
• This has to remain in C, so no C++ functionality like streams can help here

Am I missing a superior choice? Is there a good method for making a FILE * that simply focuses to an area in memory rather than on a disk? Any pointers, ideas or other assistance is enormously valuable.
