Getting Started: Building Applications with RL-ARM
//Create a file to store the directory listing
FINFO info;
Fptr = fopen ("directory.log", "w");
while (ffind ("R:*.*", &info) == 0) {
}
fclose (Fptr);
In addition to containing records for file details, the FINFO structure also
contains fields to hold a timestamp of the creation time or modification time of
the file.
typedef struct
} FINFO;
The time and calendar information is provided through two functions held in the
file
U32 fs_get_time (void);
U32 fs_get_date (void);
If you want to use time and date information within your application, you must
modify these two functions to access the real-time clock on your microcontroller.
You must also add the code to initialize the real-time clock. The file

When rebuilding the library, be careful to select either the ARM_LE (ARM7/9
Little-Endian) or Cortex as the target. The
you are using a RAM-based file system.
Exercise: Drive Functions
This project contains several examples, which demonstrate maintaining and
working with a drive volume.
