Unless explicitly stated otherwisein the description of a particular function, pointer arguments must have valid valueson a call with a zero size. On such a call, a function that locates a character finds nooccurrence, a function that compares two character sequences returns zero, and afunction that copies characters copies zero characters.Copying functionsmemcpymemmovestrcpyCopy memorySafely copy overlapping memoryCopy string310 Chapter 28 Standard C Library Reference
