  21. .SH DESCRIPTION
  22. The
  23. \fIswab\fR()
  24. function shall copy
  25. .IR nbytes
  26. bytes, which are pointed to by
  27. .IR src ,
  28. to the object pointed to by
  29. .IR dest ,
  30. exchanging adjacent bytes. The
  31. .IR nbytes
  32. argument should be even. If
  33. .IR nbytes
  34. is odd,
  35. \fIswab\fR()
  36. copies and exchanges
  37. .IR nbytes \-1
  38. bytes and the disposition of the last byte is unspecified. If copying
  39. takes place between objects that overlap, the behavior is undefined.
  40. If
  41. .IR nbytes
  42. is negative,
  43. \fIswab\fR()
  44. does nothing.
  45. .SH "RETURN VALUE"
  46. None.
