Allocate an independent copy of a C string

C: Include one extra byte for the terminating null character.

Allocate and free a typed array

C: Use sizeof on the pointed-to type and check allocation success before writing.

Allocate and initialize a structure

C: Use a compound literal assignment to initialize all ordinary structure fields.

Check an array allocation size before multiplying

C: Compare the requested element count against SIZE_MAX divided by element size.

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.
