6.2.2 Procedure

The procedure for listing the files and their respective allocated space is as follows:

1. Keep the following information for every user file created:
   1. Filename
   2. Calculate file size according to Section 4.
2. Loop over all user files and print:
   1. Filename
   2. Calculated size
3. Loop over all system/configuration files, invoke fsGetInfo() API and conclude:
   1. If return value is SL_FS_ERR_FILE_NOT_EXISTS, file does not exist and thus should not be printed. Else, the file exists and should be printed along with the allocated size
   2. If return value is SL_FS_ERR_TOKEN_IS_NOT_VALID, it means the file is secured but exists. This return value applies to the following three files:
      1. /tmp/fcon.frm
      2. /sys/pref.net
      3. /sys/smartconfigkeys.cfg

In this case, the file exists and should be printed along with the allocated size.

Figure 2 illustrates the procedure.
