WCPNCPY(3) Linux Programmer's Manual WCPNCPY(3) NAME
wcpncpy - copy a fixed-size string of wide characters, returning a pointer to its end SYNOPSIS
#include <wchar.h> wchar_t *wcpncpy(wchar_t *dest, const wchar_t *src, size_t n); Feature Test Macro Requirements for glibc (see feature_test_macros(7)): wcpncpy(): Since glibc 2.10: _POSIX_C_SOURCE >= 200809L Before glibc 2.10: _GNU_SOURCE DESCRIPTION
The wcpncpy() function is the wide-character equivalent of the stpncpy(3) function. It copies at most n wide characters from the wide- character string pointed to by src, including the terminating null wide (L' '), to the array pointed to by dest. Exactly n wide charac- ters 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' ' characters. If the length wcslen(src) is greater than or equal to n, the string pointed to by dest will not be L' ' terminated. The strings may not overlap. The programmer must ensure that there is room for at least n wide characters at dest. RETURN VALUE
wcpncpy() returns a pointer to the last wide character written, that is, dest+n-1. ATTRIBUTES
