.Sh NAME
.Nm wcsdup
.Nd save a copy of a string
.Sh LIBRARY
.Lb libc
.Sh SYNOPSIS
.In wchar.h
.Ft wchar_t *
.Fn wcsdup "const wchar_t *str"
.Sh DESCRIPTION
The
.Fn wcsdup
function
allocates sufficient memory for a copy
of the wide character string
.Fa str ,
does the copy, and returns a pointer to it.
The pointer may subsequently be used as an
argument to the function
.Xr free 3 .
.Pp
If insufficient memory is available, NULL is returned.
.Sh EXAMPLES
The following will point
.Va p
to an allocated area of memory containing the null-terminated string
.Qq foobar :
.Bd -literal -offset indent
wchar_t *p;

if (p = wcsdup(L"foobar"), p == NULL) {
	fprintf(stderr, "Out of memory.\en");
	exit(1);
}
.Ed
.Sh ERRORS
The
.Fn wcsdup
function may fail and set the external variable
.Va errno
for any of the errors specified for the library function
.Xr malloc 3 .
.Sh SEE ALSO
.Xr malloc 3 ,
.Xr free 3 ,
.Xr strdup 3 ,
.Sh HISTORY
The
.Fn wcsdup
function first appeared in
.Nx 4.0 .

.Sh NAME
.Nm wcscasecmp ,
.Nm wcsncasecmp
.Nd compare wide character strings, ignoring case
.Sh LIBRARY
.Lb libc
.Sh SYNOPSIS
.In wchar.h
.Ft int
.Fn wcscasecmp "const wchar_t *s1" "const wchar_t *s2"
.Ft int
.Fn wcsncasecmp "const wchar_t *s1" "const wchar_t *s2" "size_t len"
.Sh DESCRIPTION
The
.Fn wcscasecmp
and
.Fn wcsncasecmp
functions
compare the null-terminated strings
.Fa s1
and
.Fa s2
and return an integer greater than, equal to, or less than 0,
according to whether
.Fa s1
is lexicographically greater than, equal to, or less than
.Fa s2
after translation of each corresponding character to lower-case.
The strings themselves are not modified.
.Pp
The
.Fn wcsncasecmp
compares at most
.Fa len
characters.
.Sh SEE ALSO
.Xr wcscmp 3 ,
.Sh HISTORY
The
.Fn wcscasecmp
and
.Fn wcsncasecmp
functions first appeared in
.Nx 4.0
.Sh NOTES
If
.Fa len
is zero
.Fn wcsncasecmp
returns always 0.

P.S.
from man strncmp
NOTES
     If len is zero strncmp() returns always 0.
but 
 if (n == 0)
   return (0);
is placed AFTER asserts.

P.P.S.
If you'll add
 if (n == 0)
   return (0);
 in wcsncasecmp before asserts you can add it too.
