Manpages - wcsncat.3p

This manual page is part of the POSIX Programmer’s Manual. The Linux implementation of this interface may differ (consult the corresponding Linux manual page for details of Linux behavior), or the interface may not be implemented on Linux.

wcsncat — concatenate a wide-character string with part of another

  #include <wchar.h>
  wchar_t *wcsncat(wchar_t *restrict ws1, const wchar_t *restrict ws2,
      size_t n);

The functionality described on this reference page is aligned with the ISO C standard. Any conflict between the requirements described here and the ISO C standard is unintentional. This volume of POSIX.1‐2017 defers to the ISO C standard.

The wcsncat/() function shall append not more than /n wide-character codes (a null wide-character code and wide-character codes that follow it are not appended) from the array pointed to by ws2 to the end of the wide-character string pointed to by ws1. The initial wide-character code of ws2 shall overwrite the null wide-character code at the end of ws1. A terminating null wide-character code shall always be appended to the result. If copying takes place between objects that overlap, the behavior is undefined.

The wcsncat/() function shall return /ws1; no return value is reserved to indicate an error.

No errors are defined.
