WCPNCPY(3) Linux Programmer's Manual WCPNCPY(3)
wcpncpy - copy a fixed-size string of wide characters, returning a pointer to its end
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 char-
acters 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' ter-
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.
