class JobPolicy

Defined at line 52 of file ../../zircon/kernel/object/include/object/job_policy.h

JobPolicy is a value type that provides a space-efficient encoding of the policies defined in the

policy.h public header.

JobPolicy encodes two kinds of policy, basic and timer slack.

Basic policy is logically an array of zx_policy_basic elements. For example:

zx_policy_basic policy[] = {

{ ZX_POL_BAD_HANDLE, ZX_POL_ACTION_KILL },

{ ZX_POL_NEW_CHANNEL, ZX_POL_ACTION_ALLOW },

{ ZX_POL_NEW_FIFO, ZX_POL_ACTION_ALLOW_EXCEPTION },

{ ZX_POL_VMAR_WX, ZX_POL_ACTION_KILL }}

Timer slack policy defines the type and minimum amount of slack that will be applied to timer

and deadline events.

zx_status_t AddBasicPolicy (uint32_t mode, const zx_policy_basic_v2_t * policy, size_t count)

Merge array |policy| of length |count| into this object.

must be one of:

ZX_JOB_POL_RELATIVE - Conflicting policies are ignored and will not cause the call to fail.

ZX_JOB_POL_ABSOLUTE - If any of the policies in |policy| conflict with those in this object,

the call will fail with an error and this object will not be modified.

uint32_t QueryBasicPolicy (uint32_t condition)

Returns the action (e.g. ZX_POL_ACTION_ALLOW) for the specified |condition|.

This method asserts if |policy| is invalid, and returns ZX_POL_ACTION_DENY for all other

failure modes.

Defined at line 27 of file ../../zircon/kernel/object/job_policy.cc

uint32_t QueryBasicPolicyOverride (uint32_t condition)

Returns if the action for the specified condition can be overriden, so it returns

ZX_POL_OVERRIDE_ALLOW or ZX_POL_OVERRIDE_DENY.

void SetTimerSlack (TimerSlack slack)

Sets the timer slack policy.

|slack.amount| must be >= 0.

Defined at line 35 of file ../../zircon/kernel/object/job_policy.cc

TimerSlack GetTimerSlack ()

Returns the timer slack policy.

void IncrementCounter (uint32_t action, uint32_t condition)

Increment the kcounter for the given |action| and |condition|.

action must be

ZX_POL_ACTION_MAX and condition must be

ZX_POL_MAX.

For example: IncrementCounter(ZX_POL_ACTION_KILL, ZX_POL_NEW_CHANNEL);
