 NAME

strncat - concatenate part of two strings

 SYNOPSIS



#include <string.h>

char *strncat(char *s1, const char *s2, size_t n);

 DESCRIPTION

The strncat() function appends not more than n bytes (a null byte and bytes that follow it are not appended) from the array pointed to by s2 to the end of the string pointed to by s1. The initial byte of s2 overwrites the null byte at the end of s1. A terminating null byte is always appended to the result. If copying takes place between objects that overlap, the behaviour is undefined.

 RETURN VALUE

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

 ERRORS

No errors are defined.

 EXAMPLES

None.

 APPLICATION USAGE

None.
