fds_file_delete delete all files with given id?

[q]

Hi

I'm trying to delete all files with a given file id. Will fds_file_delete() delete all files with a given file id, or just the first one it finds?

thanks

According to the documentation...

ret_code_t fds_file_delete	(	uint16_t 	file_id	)

Function for deleting all records in a file.

This function deletes a file, including all its records. Deleted records cannot be located using fds_record_find, fds_record_find_by_key, or fds_record_find_in_file. Additionally, they can no longer be opened using fds_record_open.

Note that deleting records does not free the space they occupy in flash memory. To reclaim flash space used by deleted records, call fds_gc to run garbage collection.

This function is asynchronous. Completion is reported through an event that is sent to the registered event handler function.

The documentation is ambiguous. You can have multiple files with the same file_id, and calling (for example) fds_record_find() can return any one of those files with the provided file_id. You have to loop through fds_record_find() and fds_record_open() to find/open every file with a given file_id, so it's plausible one would have to do the same thing with fds_file_delete().
