wcpncpy - copy a fixed-size string of wide characters, returning a pointer to
its end
Návod, kniha: Linux Programmer's Manual
#define _GNU_SOURCE
#include <wchar.h>
wchar_t *wcpncpy(wchar_t *dest, const wchar_t *src, size_t n);
The
wcpncpy function is the wide-character equivalent of the
stpncpy function. It copies at most
n wide characters from the
wide-character string pointed to by
src, including the terminating
L'\0' character, 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 L'\0' characters. If the length
wcslen(src) is greater or equal to
n, the string pointed to by
dest will not be L'\0' terminated.
The strings may not overlap.
The programmer must ensure that there is room for at least
n wide
characters at
dest.
wcpncpy returns a pointer to the last wide character written, i.e.
dest + n - 1.
This function is a GNU extension.
