Subject:	strcat() ?

Hi !

I would like to know what 

strcat(a, b);

should do when b happens to be NULL.
I assume it should do nothing at all. Until v1.11m5 it did nothing, but
using v1.12m2 I had to change to

if(b)
  strcat(a,b);

to avoid concatenating some funny (nonprintable) characters to a.
Is there any possibility to find out what libc-functions do, when an
argument (pointer) is NULL ?

Tony
