STRCAT(P) POSIX Programmer's Manual STRCAT(P)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.
NAMEstrcat - 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.
