Hypercall Function Code Reference

The following table lists hypercall functions by each function's code number. The table also indicates whether each function is a rep or fast hypercall function and if the partition that calls the function requires any particular privilege or must be a particular type (for example, if the partition must be the parent partition). The HV_CALL_CODE enumeration contains all hypercall codes. For more information about hypercall functions, see Hypercall Interface.
