谁知道BrewMP平台IGallery相关的用法

[zyzlh111]

Call IGallery_MountDirs()
IGallery_Sync()
IGallery_Query()
Call IGallery_Update()
尤其后两个函数
有小例子最好。
麻烦知道帮忙解释一下～～

IGallery_Query() :这个函数中的参数请参考SQL语句，最后一个参数是输出参数，我现在正在做
结果还是不正确！

BREWMP是哪个版本呢、

[gaofeng2006]

IGallery_Query() //查询时用

Call IGallery_Update() //类似与sql中的更新语句

update set fenshu = fenshu *0.2 where name = ‘Anny’

另两个语句语法差不多
