The type of an exception observed.

Variants

General

A general exception occurred.

FatalPageFault

The process generated an unhandled page fault.

Fields

status: Status

Contains the error code returned by the page fault handler.

UndefinedInstruction

The process attempted to execute an undefined CPU instruction.

SoftwareBreakpoint

A software breakpoint was reached by the process.

HardwareBreakpoint

A hardware breakpoint was reached by the process.

UnalignedAccess

The process attempted to perform an unaligned memory access.

ThreadStarting

A thread is starting.

This exception is sent to debuggers only (ZX_EXCEPTION_CHANNEL_TYPE_DEBUGGER). The thread that generates this exception is paused until it the debugger handles the exception.

ThreadExiting

A thread is exiting.

This exception is sent to debuggers only (ZX_EXCEPTION_CHANNEL_TYPE_DEBUGGER).

This exception is different from ZX_EXCP_GONE in that a debugger can still examine thread state.

The thread that generates this exception is paused until it the debugger handles the exception.

PolicyError(PolicyCode)

This exception is generated when a syscall fails with a job policy error (for example, an invalid handle argument is passed to the syscall when the ZX_POL_BAD_HANDLE policy is enabled) and ZX_POL_ACTION_EXCEPTION is set for the policy. The thread that generates this exception is paused until it the debugger handles the exception. Additional data about the type of policy error can be found in the |synth_code| field of the report and will be a ZX_EXCP_POLICY_CODE_* value.

ProcessStarting

A process is starting.

This exception is sent to job debuggers only (ZX_EXCEPTION_CHANNEL_TYPE_JOB_DEBUGGER).

The thread that generates this exception is paused until it the debugger handles the exception.

ProcessNameChanged

A user-generated exception indicating to a debugger that the process’ name has changed.

UnknownUserGenerated

The exception was user-generated but of an unknown type.

Fields

code: u32

data: u32

Unknown

An unknown exception type.

Fields

ty: u32

code: u32

data: u32
