STRCAT(3P)                 POSIX Programmer's Manual                STRCAT(3P)

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.
NAME
       strcat - concatenate two strings
SYNOPSIS
       #include <string.h>
       char *strcat(char *restrict s1, const char *restrict s2);

DESCRIPTION
       The strcat() function shall append a copy of the string pointed  to  by
       s2  (including  the  terminating  null  byte)  to the end of the string
       pointed to by s1. The initial byte of s2 overwrites the  null  byte  at
       the end of s1. If copying takes place between objects that overlap, the
       behavior is undefined.
RETURN VALUE
       The strcat() function shall return s1; no return value is  reserved  to
       indicate an error.
ERRORS
       No errors are defined.
       The following sections are informative.
EXAMPLES
       None.
APPLICATION USAGE
       This  issue  is  aligned  with the ISO C standard; this does not affect
       compatibility with XPG3 applications. Reliable error detection by  this
       function was never guaranteed.
RATIONALE
       None.
FUTURE DIRECTIONS
       None.
