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

  23 .SH DESCRIPTION
  24 The \fBwmemcpy\fP function is the wide-character equivalent of the \fBmemcpy\fP
  25 function. It copies \fIn\fP wide characters from the array starting at
  26 \fIsrc\fP to the array starting at \fIdest\fP.
  27 .PP
  28 The arrays may not overlap; use \fBwmemmove\fP(3) to copy between overlapping
  29 arrays.
  30 .PP
  31 The programmer must ensure that there is room for at least \fIn\fP wide
  32 characters at \fIdest\fP.
  33 .SH "RETURN VALUE"
  34 \fBwmemcpy\fP returns \fIdest\fP.
