void kjb_strncat
(
	char *s1,
	const char *s2,
	size_t max_len
);

DESCRIPTION

kjb_strncat is similar to strncat but s1 always gets null terminated - IE max_len includes the null. Also, assuming that max_len is the size of the storage for s1, this routine will not write beyond that storage, including the null. This routine needs to be able to stop copying based on max_len, even if the source string has more characters. For a version that returns ERROR on possible buffer overflow, see kjb_buff_cat().

RETURNS

Unlike strncat(), this routine does not return anything.

MACROS

BUFF_CAT(char s1[], char* s2) The buffer size parameter is set to sizeof(s1). Using sizeof to set the buffer size is recomended where applicable, as the code will not be broken if the buffer size changes. HOWEVER, neither this method, nor the macro, is applicable if s1 is NOT a character array. If s1 is declared by "char* s1", then the size of s1 is the number of bytes in a character pointer (usually 8 or 4), which is NOT what is normally intended. In development mode we print a warning if the buffer size is the same as that of a pointer.
