# Virtual Machine control structure (VMCS) Field IDs

Identify the fields of the virtual machine control structure.

## Discussion

Used by the functions [`hv_vmx_vcpu_read_vmcs(_:_:_:)`](/documentation/Hypervisor/hv_vmx_vcpu_read_vmcs(_:_:_:)) and [`hv_vmx_vcpu_write_vmcs(_:_:_:)`](/documentation/Hypervisor/hv_vmx_vcpu_write_vmcs(_:_:_:)).
The VMCS fields are read-only or read-write by the Hypervisor framework, according to the following table:
