mach_port_move_member

Function - Move the specified receive right into or out of the specified port set.

SYNOPSIS

kern_return_t   mach_port_move_member
                (ipc_space_t                               task,
                 mach_port_name_t                        member,
                 mach_port_name_t                         after);

PARAMETERS

task: [in task send right] The task holding the port set and receive right.
member: [in scalar] The task's name for the receive right.
after: [in scalar] The task's name for the port set.

DESCRIPTION

The mach_port_move_member function moves a receive right into a port set. If the receive right is already a member of any other port sets, it is removed from those sets first. If the port set is MACH_PORT_NULL, then the receive right is not put into a port set, but removed from all its current port sets.

NOTES

This interface is machine word length specific because of the port name parameter.

RETURN VALUES

KERN_INVALID_NAME: member or after did not denote a right.
KERN_INVALID_RIGHT: member denoted a right, but not a receive right, or after denoted a right, but not a port set.
KERN_NOT_IN_SET: after was MACH_PORT_NULL, but member wasn't currently in a port set.
