Read the state of a VCPU.
#include <zircon/syscalls.h> zx_status_t zx_vcpu_read_state(zx_handle_t handle, uint32_t kind, void* buffer, size_t buffer_size);
zx_vcpu_read_state() reads the state of handle as specified by kind into
buffer. It is only valid to read the state of handle when execution has been
kind must be ZX_VCPU_STATE.
handle must be of type ZX_OBJ_TYPE_VCPU and have ZX_RIGHT_READ.
zx_vcpu_read_state() returns ZX_OK on success. On failure, an error value is
ZX_ERR_ACCESS_DENIED handle does not have the ZX_RIGHT_READ right.
ZX_ERR_BAD_HANDLE handle is an invalid handle.
ZX_ERR_BAD_STATE handle is in a bad state, and state can not be read.
ZX_ERR_INVALID_ARGS kind does not name a known VCPU state, buffer is an invalid pointer, or buffer_size does not match the expected size of kind.
ZX_ERR_WRONG_TYPE handle is not a handle to a VCPU.
