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.
Overview
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 wcscat() function shall append a copy of the wide-character string pointed to by ws2 (including the terminating null wide-character code) 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. If copying takes place between objects that overlap, the behavior is undefined.
Return value
The wcscat() function shall return ws1; no return value is reserved to indicate an error.
