#define KERN_SUCCESS 0
#define KERN_INVALID_ADDRESS 1
/* Specified address is not currently valid.
#define KERN_PROTECTION_FAILURE 2
/* Specified memory is valid, but does not permit the
* required forms of access.
#define KERN_NO_SPACE 3
/* The address range specified is already in use, or
* no address range of the size specified could be
#define KERN_INVALID_ARGUMENT 4
/* The function requested was not applicable to this
* type of argument, or an argument is invalid
#define KERN_FAILURE 5
/* The function could not be performed. A catch-all.
#define KERN_RESOURCE_SHORTAGE 6
/* A system resource could not be allocated to fulfill
* this request. This failure may not be permanent.
#define KERN_NOT_RECEIVER 7
/* The task in question does not hold receive rights
* for the port argument.
#define KERN_NO_ACCESS 8
/* Bogus access restriction.
#define KERN_MEMORY_FAILURE 9
/* During a page fault, the target address refers to a
* memory object that has been destroyed. This
* failure is permanent.
#define KERN_MEMORY_ERROR 10
/* During a page fault, the memory object indicated
* that the data could not be returned. This failure
* may be temporary; future attempts to access this
* same data may succeed, as defined by the memory
#define KERN_ALREADY_IN_SET 11
/* The receive right is already a member of the portset.
#define KERN_NOT_IN_SET 12
/* The receive right is not a member of a port set.
#define KERN_NAME_EXISTS 13
/* The name already denotes a right in the task.
#define KERN_ABORTED 14
/* The operation was aborted. Ipc code will
* catch this and reflect it as a message error.
#define KERN_INVALID_NAME 15
/* The name doesn't denote a right in the task.
#define KERN_INVALID_TASK 16
/* Target task isn't an active task.
#define KERN_INVALID_RIGHT 17
/* The name denotes a right, but not an appropriate right.
#define KERN_INVALID_VALUE 18
/* A blatant range error.
#define KERN_UREFS_OVERFLOW 19
/* Operation would overflow limit on user-references.
#define KERN_INVALID_CAPABILITY 20
/* The supplied (port) capability is improper.
#define KERN_RIGHT_EXISTS 21
/* The task already has send or receive rights
* for the port under another name.
#define KERN_INVALID_HOST 22
/* Target host isn't actually a host.
#define KERN_MEMORY_PRESENT 23
/* An attempt was made to supply "precious" data
* for memory that is already present in a
* memory object.
#define KERN_MEMORY_DATA_MOVED 24
/* A page was requested of a memory manager via
* memory_object_data_request for an object using
* a MEMORY_OBJECT_COPY_CALL strategy, with the
* VM_PROT_WANTS_COPY flag being used to specify
* that the page desired is for a copy of the
* object, and the memory manager has detected
* the page was pushed into a copy of the object
* while the kernel was walking the shadow chain
* from the copy to the object. This error code
* is delivered via memory_object_data_error
* and is handled by the kernel (it forces the
* kernel to restart the fault). It will not be
* seen by users.
#define KERN_MEMORY_RESTART_COPY 25
/* A strategic copy was attempted of an object
* upon which a quicker copy is now possible.
* The caller should retry the copy using
* vm_object_copy_quickly. This error code
* is seen only by the kernel.

/* An argument applied to assert processor set privilege
* was not a processor set control port.

/* The specified scheduling policy is not currently
* enabled for the processor set.

* memory object.

/* A thread is attempting to wait for an event for which
* there is already a waiting thread.
#define KERN_DEFAULT_SET 31
/* An attempt was made to destroy the default processor
#define KERN_EXCEPTION_PROTECTED 32
/* An attempt was made to fetch an exception port that is
* protected, or to abort a thread while processing a
* protected exception.

/* A ledger was required but not supplied.
#define KERN_INVALID_MEMORY_CONTROL 34
/* The port was not a memory cache control port.
