Check EEPROM capacity before a write

Arduino / C: length reports the available address count for this board.

Clear an owning pointer after releasing its allocation

C: Assigning NULL helps prevent accidental reuse through the same variable.

Copy a flash string into a bounded RAM buffer

Arduino / C: strncpy_P reads from program memory into ordinary RAM.

Create an independent copy of a byte buffer

C: Allocate the exact byte length and copy only after checking the result.

Grow an allocation without losing it on failure

C: Assign realloc to a temporary pointer so the original allocation remains available if growth fails.

Initialize a byte buffer to zero

C: memset initializes each byte to the chosen unsigned-char value.

Read 16-bit values from a flash table

Arduino / C: pgm_read_word retrieves a complete word from program memory.

Read a byte lookup table from flash

Arduino / C: PROGMEM tables require the AVR program-memory access functions.

Read and total a flash lookup table

Arduino / C: Array size can be computed at compile time even for a flash-resident table.

Reject an unsupported settings version

Arduino / C: A version byte lets firmware fall back when stored settings use another format.

Store a bounded null-terminated text setting

Arduino / C: Write a fixed buffer and explicitly terminate the retrieved copy.

Store a compact configuration record

Arduino / C: Save a struct and retrieve it with the same field layout.
