low_str_strcat

Append a string. 

l_text 		low_str_strcat ( 
		l_text 		s1,
		cl_text 		s2 
);

Return Value
Returns the destination string (@s1). No return value is reserved to indicate an error.
Parameters
s1
Null-terminated destination string
s2
Null-terminated source string
Remarks
The low_str_strcat function appends @s2 to @s1 and terminates the resulting string with a null character. 
The initial character of @s2 overwrites the terminating null character of @s1. No overflow checking is 
performed when strings are copied or appended. The behavior of low_str_strcat is undefined if the source 
and destination strings overlap.
