strncat
Synopsis
#include <string.h>
char *strncat(char *restrict s1, const char *restrict s2, size_t n);
Status
Partially implemented
Conformance
IEEE Std 1003.1-2017
Description
The strncat()
function shall append not more than n bytes (a NULL
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 NULL
character at the end of s1. A terminating NULL
character is always appended to the result. If
copying takes place between objects that overlap, the behavior is undefined.
Return value
The strncat()
function shall return s1; no return value shall be reserved to indicate an error.
Errors
No errors are defined.
