NAME

strcat - concatenate two strings

 SYNOPSIS

#include <string.h>

char *strcat(char *s1, const char *s2);

 DESCRIPTION

The strcat() function appends 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 behaviour is undefined.

 RETURN VALUE

The strcat() function returns s1; no return value is reserved to indicate an error.

 ERRORS

No errors are defined.

 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.

 FUTURE DIRECTIONS

None.
