+ STORAGE_NAME_MAX + 2u)

Function Documentation

kst_files_dir()

bool kst_files_dir

(

void

)

Make the folder, each missing level of it. False when it is not there afterwards.

kst_files_io()

const kst_store_io_t * kst_files_io

(

bool

held

)

The card for kst_card_run(): with held, the caller holds the volume (storage_hold()) for the whole request; without, the request finds no card, even one another task mounts meanwhile.

kst_files_path()

void kst_files_path	(	const char *	name,
		char *	out,
		size_t	out_size )

The full path of name inside the directory, ready for fopen().
