C语言内存数组(zbuff)

local buff = zbuff.create(1024)
    -- 可当成数组直接赋值和取值
    buff[0] = 0xAE
    log.info("zbuff", "buff[0]", buff[0])

-- 写数据write, 操作之后指针会移动,跟文件句柄一样
    buff:write("123") -- 字符串
    buff:write(0x12, 0x13, 0x13, 0x33) -- 直接写数值也可以

    -- 设置指针位置, seek
    buff:seek(5, zbuff.SEEK_CUR) -- 指针位置+5
    -- 指针位置设置为0
    buff:seek(0)                 -- 绝对地址

    -- 读数据read, 指针也会移动
    -- 读取前三个字节，即"123"
    local data = buff:read(3)
    log.info("zbuff", "data", data)

-- 清除全部数据,但指针位置不变
    buff:clear() -- 默认填0
    buff:clear(0xA5) -- 也可以指定填充的内容

-- 支持以pack库的形式写入或读取数据
    buff:seek(0)
    buff:pack(">IIHA", 0x1234, 0x4567, 0x12,"abcdefg")
    buff:seek(0)
    local cnt,a,b,c,s = buff:unpack(">IIHA10")

-- 也可以直接按类型读写数据
    local len = buff:writeI8(10)
    local len = buff:writeU32(1024)
    local i8data = buff:readI8()
    local u32data = buff:readU32()

-- 取出指定区间的数据
    local fz = buff:toStr(0,5)

-- 获取其长度
    log.info("zbuff", "len", buff:len())
    -- 获取其指针位置
    log.info("zbuff", "len", buff:used())

-- 测试writeF32, 注意, EC618系列(Air780E等), V1106会死机, 在V1107修复
    buff:seek(0, zbuff.SEEK_SET)
    buff:writeF32(1.2)
    buff:seek(0, zbuff.SEEK_SET)
    log.info("buff", "rw", "f32", buff:readF32())
