 // Zircon statuses are signed 32 bit integers. The space of values is

 // - The zero value is for the OK status.

 // - Positive values are reserved for protocol-specific error values,
 //   and will never be defined by the system.

 #define ZX_OK (0)

 // ======= Internal failures =======
 // ZX_ERR_INTERNAL: The system encountered an otherwise unspecified error
 // while performing the operation.
 #define ZX_ERR_INTERNAL (-1)

 // ZX_ERR_NOT_SUPPORTED: The operation is not implemented, supported,
 // or enabled.
 #define ZX_ERR_NOT_SUPPORTED (-2)

 // ZX_ERR_NO_RESOURCES: The system was not able to allocate some resource
 // needed for the operation.
 #define ZX_ERR_NO_RESOURCES (-3)

 // ZX_ERR_NO_MEMORY: The system was not able to allocate memory needed
 // for the operation.
 #define ZX_ERR_NO_MEMORY (-4)

 // -5 used to be ZX_ERR_CALL_FAILED.

 // ZX_ERR_INTERNAL_INTR_RETRY: The system call was interrupted, but should be
 // retried.  This should not be seen outside of the VDSO.
 #define ZX_ERR_INTERNAL_INTR_RETRY (-6)

 // ======= Parameter errors =======
 // ZX_ERR_INVALID_ARGS: an argument is invalid, ex. null pointer
 #define ZX_ERR_INVALID_ARGS (-10)

 // ZX_ERR_BAD_HANDLE: A specified handle value does not refer to a handle.
 #define ZX_ERR_BAD_HANDLE (-11)

 // ZX_ERR_WRONG_TYPE: The subject of the operation is the wrong type to
 // perform the operation.
 // Example: Attempting a message_read on a thread handle.
 #define ZX_ERR_WRONG_TYPE (-12)

 // ZX_ERR_BAD_SYSCALL: The specified syscall number is invalid.
 #define ZX_ERR_BAD_SYSCALL (-13)

 // ZX_ERR_OUT_OF_RANGE: An argument is outside the valid range for this
 // operation.
 #define ZX_ERR_OUT_OF_RANGE (-14)

 // ZX_ERR_BUFFER_TOO_SMALL: A caller provided buffer is too small for
 // this operation.
 #define ZX_ERR_BUFFER_TOO_SMALL (-15)

 // ======= Precondition or state errors =======
 // ZX_ERR_BAD_STATE: operation failed because the current state of the
 // object does not allow it, or a precondition of the operation is
 // not satisfied
 #define ZX_ERR_BAD_STATE (-20)

 // ZX_ERR_TIMED_OUT: The time limit for the operation elapsed before
 // the operation completed.
 #define ZX_ERR_TIMED_OUT (-21)

 // ZX_ERR_SHOULD_WAIT: The operation cannot be performed currently but
 // potentially could succeed if the caller waits for a prerequisite
 // to be satisfied, for example waiting for a handle to be readable
 // or writable.
 // Example: Attempting to read from a channel that has no
 // messages waiting but has an open remote will return ZX_ERR_SHOULD_WAIT.
 // Attempting to read from a channel that has no messages waiting
 // and has a closed remote end will return ZX_ERR_PEER_CLOSED.
 #define ZX_ERR_SHOULD_WAIT (-22)

 // ZX_ERR_CANCELED: The in-progress operation (e.g. a wait) has been
 // canceled.
 #define ZX_ERR_CANCELED (-23)

 // ZX_ERR_PEER_CLOSED: The operation failed because the remote end of the
 // subject of the operation was closed.
 #define ZX_ERR_PEER_CLOSED (-24)

 // ZX_ERR_NOT_FOUND: The requested entity is not found.
 #define ZX_ERR_NOT_FOUND (-25)

 // ZX_ERR_ALREADY_EXISTS: An object with the specified identifier
 // already exists.
 // Example: Attempting to create a file when a file already exists
 // with that name.
 #define ZX_ERR_ALREADY_EXISTS (-26)

 // ZX_ERR_ALREADY_BOUND: The operation failed because the named entity
 // is already owned or controlled by another entity. The operation
 // could succeed later if the current owner releases the entity.
 #define ZX_ERR_ALREADY_BOUND (-27)

 // ZX_ERR_UNAVAILABLE: The subject of the operation is currently unable
 // to perform the operation.
 // Note: This is used when there's no direct way for the caller to
 // observe when the subject will be able to perform the operation
 // and should thus retry.
 #define ZX_ERR_UNAVAILABLE (-28)

 // ======= Permission check errors =======
 // ZX_ERR_ACCESS_DENIED: The caller did not have permission to perform
 // the specified operation.
 #define ZX_ERR_ACCESS_DENIED (-30)

 // ======= Input-output errors =======
 // ZX_ERR_IO: Otherwise unspecified error occurred during I/O.
 #define ZX_ERR_IO (-40)

 // ZX_ERR_REFUSED: The entity the I/O operation is being performed on
 // rejected the operation.
 // Example: an I2C device NAK'ing a transaction or a disk controller
 // rejecting an invalid command, or a stalled USB endpoint.
 #define ZX_ERR_IO_REFUSED (-41)

 // ZX_ERR_IO_DATA_INTEGRITY: The data in the operation failed an integrity
 // check and is possibly corrupted.
 // Example: CRC or Parity error.
 #define ZX_ERR_IO_DATA_INTEGRITY (-42)

 // ZX_ERR_IO_DATA_LOSS: The data in the operation is currently unavailable
 // and may be permanently lost.
 // Example: A disk block is irrecoverably damaged.
 #define ZX_ERR_IO_DATA_LOSS (-43)

 // ZX_ERR_IO_NOT_PRESENT: The device is no longer available (has been
 // unplugged from the system, powered down, or the driver has been
 // unloaded)
 #define ZX_ERR_IO_NOT_PRESENT (-44)

 // ZX_ERR_IO_OVERRUN: More data was received from the device than expected.
 // Example: a USB "babble" error due to a device sending more data than
 // the host queued to receive.
 #define ZX_ERR_IO_OVERRUN (-45)

 // ZX_ERR_IO_MISSED_DEADLINE: An operation did not complete within the required timeframe.
 // Example: A USB isochronous transfer that failed to complete due to an overrun or underrun.
 #define ZX_ERR_IO_MISSED_DEADLINE (-46)

 // ZX_ERR_IO_INVALID: The data in the operation is invalid parameter or is out of range.
 // Example: A USB transfer that failed to complete with TRB Error
 #define ZX_ERR_IO_INVALID (-47)

 // ======== Filesystem Errors ========
 // ZX_ERR_BAD_PATH: Path name is too long.
 #define ZX_ERR_BAD_PATH (-50)

 // ZX_ERR_NOT_DIR: Object is not a directory or does not support
 // directory operations.
 // Example: Attempted to open a file as a directory or
 // attempted to do directory operations on a file.
 #define ZX_ERR_NOT_DIR (-51)

 // ZX_ERR_NOT_FILE: Object is not a regular file.
 #define ZX_ERR_NOT_FILE (-52)

 // ZX_ERR_FILE_BIG: This operation would cause a file to exceed a
 // filesystem-specific size limit
 #define ZX_ERR_FILE_BIG (-53)

 // ZX_ERR_NO_SPACE: Filesystem or device space is exhausted.
 #define ZX_ERR_NO_SPACE (-54)

 // ZX_ERR_NOT_EMPTY: Directory is not empty.
 #define ZX_ERR_NOT_EMPTY (-55)

 // ======== Flow Control ========
 // These are not errors, as such, and will never be returned
 // by a syscall or public API.  They exist to allow callbacks
 // to request changes in operation.
 //
 // ZX_ERR_STOP: Do not call again.
 // Example: A notification callback will be called on every
 // event until it returns something other than ZX_OK.
 // This status allows differentiation between "stop due to
 // an error" and "stop because the work is done."
 #define ZX_ERR_STOP (-60)

 // ZX_ERR_NEXT: Advance to the next item.
 // Example: A notification callback will use this response
 // to indicate it did not "consume" an item passed to it,
 // but by choice, not due to an error condition.
 #define ZX_ERR_NEXT (-61)

 // ZX_ERR_ASYNC: Ownership of the item has moved to an asynchronous worker.
 //
 // Unlike ZX_ERR_STOP, which implies that iteration on an object
 // should stop, and ZX_ERR_NEXT, which implies that iteration
 // should continue to the next item, ZX_ERR_ASYNC implies
 // that an asynchronous worker is responsible for continuing iteration.
 //
 // Example: A notification callback will be called on every
 // event, but one event needs to handle some work asynchronously
 // before it can continue. ZX_ERR_ASYNC implies the worker is
 // responsible for resuming iteration once its work has completed.
 #define ZX_ERR_ASYNC (-62)

 // ======== Network-related errors ========

 // ZX_ERR_PROTOCOL_NOT_SUPPORTED: Specified protocol is not
 // supported.
 #define ZX_ERR_PROTOCOL_NOT_SUPPORTED (-70)

 // ZX_ERR_ADDRESS_UNREACHABLE: Host is unreachable.
 #define ZX_ERR_ADDRESS_UNREACHABLE (-71)

 // ZX_ERR_ADDRESS_IN_USE: Address is being used by someone else.
 #define ZX_ERR_ADDRESS_IN_USE (-72)

 // ZX_ERR_NOT_CONNECTED: Socket is not connected.
 #define ZX_ERR_NOT_CONNECTED (-73)

 // ZX_ERR_CONNECTION_REFUSED: Remote peer rejected the connection.
 #define ZX_ERR_CONNECTION_REFUSED (-74)

 // ZX_ERR_CONNECTION_RESET: Connection was reset.
 #define ZX_ERR_CONNECTION_RESET (-75)

 // ZX_ERR_CONNECTION_ABORTED: Connection was aborted.
 #define ZX_ERR_CONNECTION_ABORTED (-76)

 // ======= VDSO-private errors =======

 // ZX_ERR_INTERNAL_INTR_KILLED: A task was killed during an operation.
 #define ZX_ERR_INTERNAL_INTR_KILLED (-502)
