390Sstevel@tonic-gate  *  NAME
400Sstevel@tonic-gate  *	strmove - copy a string, permitting overlaps

420Sstevel@tonic-gate  *  SYNOPSIS
430Sstevel@tonic-gate  *	void strmove(char *to, char *from)
440Sstevel@tonic-gate  *
450Sstevel@tonic-gate  *  DESCRIPTION
460Sstevel@tonic-gate  *	strmove() acts exactly like strcpy() with the additional
470Sstevel@tonic-gate  *	guarantee that it will work with overlapping strings.
480Sstevel@tonic-gate  *	It does it left-to-right, a byte at a time.
