Following code contains function called count which is ensuring the consistency of shar Assume that Count function can be called by several of thread and doesn't allow cnt bec Write pthread$\_$mutex$\_$lock and pthread$\_$mutex$\_$unlock functions into critical sections of $f$

Itdefine NITER $1000000$

pthread$\_$mutex$\_$t nutex $=$ PTHREAD$\_$MUTEX$\_$INITIALIZER;

int cnt $=0$;

void $*$ count$($void $*$ a$)$

$\{$

int $1,$ tmp;

for NITER; $i+t$

$tmp=$ cnt

$tmp=tmp+1$;

cnt $=$ tmp;
