                (task_t                                    task,
                 security_port_t                  host_security,
                 security_token_t                security_token,
                 ledger_port_array_t                    ledgers,
                 boolean_t                       inherit_memory,
                 task_t                                  task_t);

PARAMETERS

parent_task

[in task send right] The port for the task from which to draw the child task's port rights and address space.

host_security

[in security send right] The host's security port.

security_token

[in scalar] The task's security token.

ledgers

[pointer to in array of ledger send rights] The set of ledgers from which the task will draw its resources.

inherit_memory

[in scalar] Address space inheritance indicator. If true, the child task in- herits the address space of the parent task. If false, the kernel assigns the child task an empty address space.

child_task

[out task send right] The kernel-assigned port name for the new task.

DESCRIPTION

The task_create_security_token function creates a new task from parent_task with an explicit security token, returning the name of the new task in the parameter specified by child_task. Other than the security token, the child task is as if created by task_create.

NOTES

The host security port is a privileged port given to the system bootstrap task for the use of this call.

RETURN VALUES

KERN_INVALID_SECURITY

The value of host_security does not specify the security port for the host on which task lies.
