wcpncpy(3) Library Functions Manual wcpncpy(3) wcpncpy - LIBRARY Standard C library (libc, -lc) #include wchar_t *wcpncpy(wchar_t dest[restrict .n], const wchar_t src[restrict .n], size_t n); glibc (. feature_test_macros(7)): wcpncpy(): glibc 2.10: _POSIX_C_SOURCE >= 200809L glibc 2.10: _BSD_SOURCE 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'\0'), 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 than or equal to n, the string pointed to by dest will not be L'\0' terminated. . , dest n . wcpncpy() , dest+n-1. attributes(7). +----------------------------+----------------------------------------------------------+--------------------------+ | | | | +----------------------------+----------------------------------------------------------+--------------------------+ |wcpncpy() | | MT-Safe | +----------------------------+----------------------------------------------------------+--------------------------+ POSIX.1-2008. . stpncpy(3), wcsncpy(3) Azamat Hackimov Yuri Kozlov ; GNU 3 , . . , , .
