fanalyse

#include <rtl.h>

int fanalyse  (
    const char *drive);    /* drive to analyze */

The function fanalyse examines the Embedded Flash File System and checks for file fragmentation. The parameter drive is a string pointer denoting the drive letter.

The function is included in the RL-FlashFS library. The prototype is defined in the file rtl.h.

The following values are allowed for the parameter drive:

A number between 0 and 255 representing the fragmentation factor.

• 0 - no files are fragmented. Cannot be checked, for example when applied upon FAT media.
• 255 - most files are fragmented.

If the fragmentation factor is high (above 50), consider defragmenting the drive.

fcheck, fdefrag

#include <rtl.h>

void free_space (void) {

  printf ("\nFree space before defrag: %d bytes.", ffree(""));
  if (fanalyse("") > 50) {
    fdefrag ("");
  }
  printf ("\nFree space after defrag: %d bytes.", ffree(""));
}
