Actually, POSIX _is_ explicit about null pointer checks:
http://www.opengroup.org/onlinepubs/009695399/functions/xsh_chap02_01.html
"Each of the following statements shall apply unless explicitly stated
otherwise in the detailed descriptions that follow:
"1. If an argument to a function has an invalid value (such as a value
outside the domain of the function, or a pointer outside the address space
of the program, or a null pointer), the behavior is undefined."
