fatfs 获取文件目录

yhz · 发表于 2012-12-21 15:06:08

我使用 scan_files (char* path) 此函数获取文件目录，我联系调用两次，第二次却读不到文件目录了，这是为什么啊？

FRESULT scan_files (char* path)

{

FRESULT res;

FILINFO fno;

DIR dir;

int i,i_name = 0;

char *fn;

#if _USE_LFN

static char lfn[_MAX_LFN * (_DF1S ? 2 : 1) + 1];

fno.lfname = lfn;

fno.lfsize = sizeof(lfn);

#endif

disk_initialize(0);

f_mount(0, &fs);

res = f_opendir(&dir, path);

if (res == FR_OK) {

i = strlen(path);

for (;;) {

res = f_readdir(&dir, &fno);

if (res != FR_OK || fno.fname[0] == 0) break;

i_name ++;

if (fno.fname[0] == '.') continue;

#if _USE_LFN

fn = *fno.lfname ? fno.lfname : fno.fname;

#else

fn = fno.fname;

#endif

if (fno.fattrib & AM_DIR) {

sprintf(&path, "/%s", fn);

res = scan_files(path);

if (res != FR_OK) break;

path = 0;

} else {

printf("%s/%s\n", path, fn);

stringcopy(Files_Pro[i_name - 1].name, fno.fname);

Files_Pro[i_name - 1].time = fno.fdate; //读取文件建立时间

Files_Pro[i_name - 1].size = fno.fsize;

}

f_close(&fsrc);

}

}

Files_count = i_name;

f_mount(0,NULL);

return res;

}
