关于全志V3文件命名问题

这年头什么奇葩需求都有，这不好好地文件是年月日时分秒组成的，他偏要文件个数计数！！！

需求：3. 视频文件名称：KB0001，后4位数值随文件个数递增4. 照片文件名称：K0000001，后7位数值随文件个数递

错误方式

  //我脑海闪过的第一概念，就是改命名就可以了。  //于是我就这样操作了一波将文件命名直接计数  #if 0    sprintf(buf, "%s%04d%02d%02d_%02d%02d%02d%s%s%s",path,tm->tm_year + 1900, tm->tm_mon + 1,        tm->tm_mday, tm->tm_hour,tm->tm_min, tm->tm_sec, camType, suffix, fileType);    #else    if(strncmp(fileType,EXT_PIC_JPG,4) == 0)        {            //sscanf(buf, "%[0-9]4d%[0-9]3d",picture_num_there , picture_num_four);              //db_msg("%s",buf);            db_msg("--EXT_PIC_JPG-%d----%d",picture_num_there, picture_num_four);            picture_num_four++;            if(picture_num_four >9999){                    picture_num_four=0;                    picture_num_there++;                        if(picture_num_there >999){                            picture_num_there=0;                            }            }            sprintf(buf, "%sK%04d%03d%s%s",path, picture_num_there, picture_num_four,suffix, fileType);        }    else        {                picture_num_four++;                        if(picture_num_four >9999){                            picture_num_four=0;                            }            sprintf(buf, "%sKB%04d%s%s",path, video_num_four,suffix, fileType);         }    #endif

//命名之后，由于机器掉电，不管是栈还是堆，数据都会丢失，除非是保存在文件中。。。//但是我脑海想到是开始去获取文件名，（文件是DBCtrl做的数据包装），我直接获取是上次拍照的最后一张，这样照片排序的问题就解决了(那是我考虑得太简单)//我把获取文件信息函数加到开机函数构造哪里，并加了几句代码    strcpy(buf,dbRecord.file);    sscanf(buf, "/mnt/extsd/photo/K%[^.].jpg",tmp2);    sscanf(tmp2, "%3d%4d",&mSTM->picture_num_four,&mSTM->picture_num_there);    db_msg("buf=%s ,tmp1=%s,tmp2=%s",buf,tmp1,tmp2);    db_msg("--EXT_PIC_JPG-%d----%d",mSTM->picture_num_four, mSTM->picture_num_there);

正确处理方式

//我想到视频又要出处理，而且如果SD卡中有其他不是本机拍的照片那我写的函数不就有问题了吗//赶紧的计数信息保存到文件中//不知道为什么全志的menu.cfg增加信息里面的（unsigned int）count，current大于99突然就会报这种错误，缓冲区溢出的错误，然后就死机。V/ResourceManager.cpp(   61): <line[4173] syncConfigureToDisk()> buf is 4Fbc    (   61): *** vsprintf buffer overflow detected ***Fbc    (   61): Fatal signal 6 (SIGABRT) at 0x0000003d (code=0), thread 61 (sdv)I/DEBUG   (   59): *** *** *** *** *** *** *** *** *** *** *** *** *** *** *** ***I/DEBUG   (   59): Build fingerprint: 'softwinners/crane_sl609/crane-sl609:4.2.2/JDQ39/eng.quhongbo.20161230.091807:eng/test-keys'I/DEBUG   (   59): Revision: '0'I/DEBUG   (   59): pid: 61, tid: 61, name: sdv  >>> /system/bin/sdv <<<I/DEBUG   (   59): signal 6 (SIGABRT), code -6 (?), fault addr --------//但也难不住我，我把它分开保存就是
