## NAME

vcpu_resume - resume execution of a VCPU

## SYNOPSIS

<!-- Updated by update-docs-from-abigen, do not edit. -->

```
#include <zircon/syscalls.h>
#include <zircon/syscalls/port.h>

zx_status_t zx_vcpu_resume(zx_handle_t handle, zx_port_packet_t* packet);
```

## DESCRIPTION

`zx_vcpu_resume()` begins or resumes execution of *handle*, and blocks until it has
paused execution. On pause of execution, *packet* is populated with reason for
the pause. After handling the reason, execution may be resumed by calling
`zx_vcpu_resume()` again.

N.B. Execution of a *handle* must be resumed on the same thread it was created on.

## RIGHTS

<!-- Updated by update-docs-from-abigen, do not edit. -->

*handle* must be of type **ZX_OBJ_TYPE_VCPU** and have **ZX_RIGHT_EXECUTE**.

## RETURN VALUE

`zx_vcpu_resume()` returns **ZX_OK** on success. On failure, an error value is
returned.

## ERRORS

**ZX_ERR_ACCESS_DENIED** *handle* does not have the **ZX_RIGHT_EXECUTE** right.

**ZX_ERR_BAD_HANDLE** *handle* is an invalid handle.

**ZX_ERR_BAD_STATE** *handle* is in a bad state, and can not be executed.

**ZX_ERR_CANCELED** *handle* execution was canceled while waiting on an event.

**ZX_ERR_INTERNAL** There was an error executing *handle*.

**ZX_ERR_INVALID_ARGS** *packet* is an invalid pointer.

**ZX_ERR_NOT_SUPPORTED** An unsupported operation was encountered while
executing *handle*.

**ZX_ERR_WRONG_TYPE** *handle* is not a handle to a VCPU.
