NAME 🖥️ wcsncpy 🖥️

copy a fixed-size string of wide characters

LIBRARY

Standard C library (libc, -lc)

SYNOPSIS

#include <wchar.h>
wchar_t *wcsncpy(wchar_t dest[restrict .n],
 const wchar_t src[restrict .n],
 size_t n);

DESCRIPTION

The wcsncpy() function is the wide-character equivalent of the strncpy(3) function. It copies at most n wide characters from the wide-character string pointed to by src, including the terminating null wide character (L’�’), to the array pointed to by dest. Exactly n wide characters are written at dest. If the length wcslen(src) is smaller than n, the remaining wide characters in the array pointed to by dest are filled with null wide characters. If the length wcslen(src) is greater than or equal to n, the string pointed to by dest will not be terminated by a null wide character.

The strings may not overlap.

The programmer must ensure that there is room for at least n wide characters at dest.

RETURN VALUE

wcsncpy() returns dest.
