Several language constructs in C are there specifically to diddle bits 
in hardware.  Bit fields were in the earliest implementations of the 
language to allow you to address individual bit control and status bits 
in memory-mapped device controllers.  The volatile keyword is there to 
deal with bits which change value on their own (as hardware status 
registers do).

And, why do you need a library routine to touch a memory location, when 
you can just dereference an integer? :-)
