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'\0'), 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 .
