Getting a Seg Fault when reading in Data from a text file in C

Question

I'm trying to take information from a text file and read it in, in my main i get the length of the file in bytes, as well as the name of the file to ensure that it exists, and pass it to this method.

I have some test code in there for seeing where the issue is, but I can not seem to see where the seg fault comes from, the fgetc return value matches the value its stored in which is the only thing I can think of.

uint32 getCode(char *fileA, int count){
   //creating variables to store the data we are reading in
   int buffer = 0;
   register uint64 total = 0;

   //opening with rb ensures that all file types will be readable
   FILE *file;
   if(file= fopen(fileA, "rb")){
      printf("\nfilename: %s\ncount: %d\n",fileA,count);
   }
   // while loop reading in 32 bits at a time or 4 bytes
   while(count > 0){
      buffer = fgetc(file);
      count--;
      printf("\n%s", buffer);
   }

   fclose(file);
   return 1;
}

Answer 1

The segmentation fault comes from printf("\n%s", buffer); -- your buffer is not a string, and you may get much better results printing using format '%c'

And yeah, the comment // while loop reading in 32 bits at a time or 4 bytes is a bit misleading, since you're reading 1 byte at a time.
