  17 .SH NAME
  18 wmemcpy \- copy an array of wide-characters
  19 .SH SYNOPSIS
  20 .nf
  21 .B #include <wchar.h>

  25 .SH DESCRIPTION
  26 The
  27 .BR wmemcpy ()
  28 function is the wide-character equivalent of the
  29 .BR memcpy (3)
  30 function.
  31 It copies
  32 .I n
  33 wide characters from the array starting at
  34 .I src
  35 to the array starting at
  36 .IR dest .
  37 .PP
  38 The arrays may not overlap; use
  39 .BR wmemmove (3)
  40 to copy between overlapping
  41 arrays.
  42 .PP
  43 The programmer must ensure that there is room for at least
  44 .I n
  45 wide
  46 characters at
  47 .IR dest .
