WCPNCPY(3) Linux Programmers 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 stp
ncpy(3) 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 char
acters at dest.
wcpncpy() returns a pointer to the last wide character written, that
is, dest + n - 1.
This function is a GNU extension.
