Citeren Frédéric Bohé <[email protected]>:
+ static const char *path = getfullpath(PATH_ETC);
getfullpath is allocating memory with xstrdup. Doesn't this line produce
a memory leak ?
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
