fdelete

#include <rtl.h>

int fdelete  (
  const char *filename);    /* file to delete */

The function fdelete removes a file or folder from EFS or FAT file system. The parameter filename is a character pointer specifying the file or folder to be deleted.

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

The argument filename can contain:

• A file name.
• A drive prefix. If the drive prefix is omitted, the Default System drive specified in the file File_Config.c is used.
• A file path. Use the escape character "\" when specifying a path. To delete a folder, terminate the parameter with a backslash.
• A combination of the above.

The following drive prefixes are allowed:

• 0 - on success.
• non-zero value - on failure. File not found. Folder not empty.
