SdFat Library what is dir_t*? I'm using the SDFat library and the FatFile type has the functions:


  bool FatFile::dirEntry(dir_t* dir)
  
  Return a file's directory entry.
  
  Parameters
  
  
    [out] dir    Location for return of the file's directory entry.
  
  
  Returns
  
  
    The value true is returned for success and the value false is returned
    for failure.
  


And


  uint8_t FatFile::dirName(const dir_t *dir, char *name)
  
  Format the name field of dir into the 13 byte array name in standard
  8.3 short name format.
  
  Parameters
  
  
    [in] dir The directory structure containing the name.
    
    [out]    name    A 13 byte char array for the formatted name.
  
  
  Returns
  
  
    length of the name.
  


From what I understand, I should be able to pass something like this into the functions:

dir_t Bass;
char dName [13];
FatFile BrowseFile;
BrowseFile.open("/Folder1/File1.txt", O_RDONLY);
Serial.print(BrowseFile.dirEntry(&amp;*Bass));
Serial.print(BrowseFile.dirName(Bass,*dName));
Serial.println(dName);


to which the program should output

1
[Folder1's 8.3 name length]
[Folder1's 8.3 name]


However, I'm getting an error and I can't find any included examples that use these two functions in a sketch. if someone could explain what I'm doing wrong, it would be greatly appreciated.
dir_t * is a pointer to a variable of type dir_t.

I don't know the API to which you refer, but the format for passing it would be:

dir_t Bass;
char dName[13];
BrowseFile.dirEntry(&amp;Bass);
BrowseFile.dirName(&amp;Bass, dName);
Serial.println(dName);
