Пролог (Prolog)
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.
Имя (Name)
strncat — concatenate a string with part of another
Синопсис (Synopsis)
#include <string.h>
char *strncat(char *restrict s1, const char *restrict s2, size_t n);
Описание (Description)
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 strncat() function shall append not more than n bytes (a NUL
character and bytes that follow it are not appended) from the
array pointed to by s2 to the end of the string pointed to by s1.
The initial byte of s2 overwrites the NUL character at the end of
s1. A terminating NUL character is always appended to the
result. If copying takes place between objects that overlap, the
behavior is undefined.
Возвращаемое значение (Return value)
The strncat() function shall return s1; no return value shall be
reserved to indicate an error.
Ошибки (Error)
No errors are defined.
