wcsncat(3)               Library Functions Manual              wcsncat(3)

NAME         top

       wcsncat - concatenate two wide-character strings

LIBRARY         top

       Standard C library (libc, -lc)

SYNOPSIS         top

       #include <wchar.h>

       wchar_t *wcsncat(size_t n;
                        wchar_t *restrict dest,
                        const wchar_t src[restrict n],
                        size_t n);

DESCRIPTION         top

       The wcsncat() function is the wide-character equivalent of the
       strncat(3) function.  It copies at most n wide characters from the
       wide-character string pointed to by src to the end of the wide-
       character string pointed to by dest, and adds a terminating null
       wide character (L'\0').

       The strings may not overlap.

       The programmer must ensure that there is room for at least
       wcslen(dest)+n+1 wide characters at dest.

RETURN VALUE         top

       wcsncat() returns dest.
