Possible solution:

                Status = fseek(SrcFileDesc, SeekOffset, SEEK_SET);
                if (Status != 0)
                {
                    printf("Error locating Section Header #%d in file '%s'\n", SectionIndex, SrcFilename);
                    return FAILED;
                }
                else 
                {
                    fseek(SrcFileDesc, SeekOffset, SEEK_SET);
                }
