safe_free

#define safe_free

(

x

)

while ((x)) { free_const((x)); (x) = nullptr; }

safe_free() - same as free(3). Used for portability. Accepts pointers to dynamically allocated const data. Will not call free(3) if the pointer is nullptr. Sets the pointer to nullptr on completion.

Use xfree() if the pointer does not need to be set afterward.

Define failure_notify to receive error message. otherwise perror() is used to display it.

xfree() - same as free(3). Used for portability. Accepts pointers to dynamically allocated const data. Will not call free(3) if the pointer is nullptr.

Pointer is left with a value on completion. Use safe_free() if the pointer needs to be set to nullptr afterward.
