PROLOG

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

NAME

12       strcat - concatenate two strings
13

SYNOPSIS

15       #include <string.h>
16
17       char *strcat(char *restrict s1, const char *restrict s2);
18
19

DESCRIPTION

21       The strcat() function shall append a copy of the string pointed  to  by
22       s2  (including  the  terminating  null  byte)  to the end of the string
23       pointed to by s1. The initial byte of s2 overwrites the  null  byte  at
24       the end of s1. If copying takes place between objects that overlap, the
25       behavior is undefined.
26

RETURN VALUE

28       The strcat() function shall return s1; no return value is  reserved  to
29       indicate an error.
30

ERRORS

32       No errors are defined.

APPLICATION USAGE

40       This  issue  is  aligned  with the ISO C standard; this does not affect
41       compatibility with XPG3 applications. Reliable error detection by  this
42       function was never guaranteed.
43

RATIONALE

45       None.
46

FUTURE DIRECTIONS

48       None.
