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
characters in the array pointed to by dest are filled with L'\0' char-
acters. 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 char-
acters at dest.
wcpncpy returns a pointer to the last wide character written, i.e.
dest + n - 1.
This function is a GNU extension.
