vcpu_write_state - write the state of a VCPU
#include <zircon/syscalls.h> #include <zircon/syscalls/hypervisor.h> zx_status_t zx_vcpu_write_state(zx_handle_t vcpu, uint32_t kind, const void* buffer, uint32_t len);
vcpu_write_state() writes the state of vcpu as specified by kind from buffer. It is only valid to write the state of vcpu when execution has been paused.
kind may be ZX_VCPU_STATE or ZX_VCPU_IO.
vcpu_write_state() returns ZX_OK on success. On failure, an error value is returned.
ZX_ERR_ACCESS_DENIED vcpu does not have the ZX_RIGHT_WRITE right.
ZX_ERR_BAD_HANDLE vcpu is an invalid handle.
ZX_ERR_BAD_STATE vcpu is in a bad state, and state can not be written.
ZX_ERR_INVALID_ARGS kind does not name a known VCPU state, buffer is an invalid pointer, or len does not match the expected size of kind.
ZX_ERR_WRONG_TYPE vcpu is not a handle to a VCPU.
