1. 文件读写
fseek(fp, Elf32SectionHeader.sh_offset, SEEK_SET);
fread(lpStringTable, Elf32SectionHeader.sh_size, 1, fp);
fseek(fp, Elf32Header.e_shoff, SEEK_SET);
2. 字符数组

0xD5, 0x1A, 0x04, 0x3A, 0x16, 0x68, 0x76, 0x19, 0x01, 0x3E, 0xB7, 0x46
};
upx_byte *p = getLoader();
lsize = getLoaderSize();
unsigned raw_lsize = lsize;

updateLoader(fo);

printf(" \n");
}

}
//hex_print(p, lsize);
printf("----- loader size : %d , raw_size: %d \n,", lsize, raw_lsize);
