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:
_XOPEN_SOURCE >= 700 || _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 (Laq\0aq), 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 Laq\0aq characters. If the length wcslen(src) is greater than or equal to n, the string pointed to by dest will not be Laq\0aq 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

Multithreading (see pthreads(7) )

The wcpncpy() function is thread-safe.

Conforming to
