  20. .SH DESCRIPTION
  21. The functionality described on this reference page is aligned with the
  22. ISO\ C standard. Any conflict between the requirements described here and the
  23. ISO\ C standard is unintentional. This volume of POSIX.1\(hy2017 defers to the ISO\ C standard.
  24. .P
  25. The
  26. \fImemmove\fR()
  27. function shall copy
  28. .IR n
  29. bytes from the object pointed to by
  30. .IR s2
  31. into the object pointed to by
  32. .IR s1 .
  33. Copying takes place as if the
  34. .IR n
  35. bytes from the object pointed to by
  36. .IR s2
  37. are first copied into a temporary array of
  38. .IR n
  39. bytes that does not overlap the objects pointed to by
  40. .IR s1
  41. and
  42. .IR s2 ,
  43. and then the
  44. .IR n
  45. bytes from the temporary array are copied into the object pointed to by
  46. .IR s1 .
  47. .SH "RETURN VALUE"
  48. The
  49. \fImemmove\fR()
  50. function shall return
  51. .IR s1 ;
