I don't get it?
Having static data like:
static int mad_portid = -1;
static int class_agent[MAX_CLASS];
Makes some functions dangerous.
Then the other interface does not provide any locking... Oh I guess you are
saying that "a" is ibmad_port thingy... Then yes if you don't have threads
modifying it at the same time you will be ok.
