The pf_readdir function reads directory entries.
FRESULT pf_readdir ( DIR* DirObject, /* [IN] Pointer to the open directory object */ FILINFO* FileInfo /* [OUT] Pointer to the file information structure */ );
The pf_readdir function reads directory entries in sequence. All items in the directory can be read by calling pf_readdir function repeatedly. When all directory entries have been read and no item to read, the function returns a null string into f_name[] member without any error. When a null pointer is given to the FileInfo, the read index of the directory object will be rewinded.
FRESULT scan_files (char* path) { FRESULT res; FILINFO fno; DIR dir; int i; res = pf_opendir(&dir, path); if (res == FR_OK) { i = strlen(path); for (;;) { res = pf_readdir(&dir, &fno); if (res != FR_OK || fno.fname[0] == 0) break; if (fno.fattrib & AM_DIR) { sprintf(&path[i], "/%s", fno.fname); res = scan_files(path); if (res != FR_OK) break; path[i] = 0; } else { printf("%s/%s\n", path, fno.fname); } } } return res; }
