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.
