Information from utListDir command
« on: March 09, 2015, 03:24:30 PM »
Hi Mark,
  I was thinking about using the ulListDir command to go through the whole sd card (trailing into directories and collecting files), is there a way to detect after the call if the entry is directory or a file? If so are there any variables that can get the file, or directory  name ?

Thanks
Neil

To check the entry type you can use:

if (fileList.ucFileAttributes & DIR_ATTR_ARCHIVE) { // if a file
}


The list entry also contains some string details about the entry in the list buffer, where the name of file/directory string is present. From these details a pointer can be set to the start of the name (last entry in the string) as follows:

CHAR *ptrFileName = &cBuffer[fileList.usStringLength - fileList.ucNameLength]; // set pointer to null terminated file name
where cBuffer[] is the buffer that you configured for the listing to be placed into.

As reference see the SD card serial loader (in Kinetis project) which performs an optional wildcard file search using the methods above.

Regards

Mark
