Nope.

Whenever you do an assignment to a static variable, this is only done  
once. So the getfullpath() function will be called the first time you  
enter this function and afterwards, the result of this call will be  
used. Unlike an ordinary automatic variable, static variables defined  
in functions are preserved between calls.

We usually prefer static local variables over global ones, because it  
prevents namespace conflicts and also prevents other function from  
messing with the variables.

Best regards, Arjen
