qvm_state_block

Base structure to describe a data element (typically in the guest)

Synopsis:

#include <qvm/types.h>
struct qvm_state_block {
    uint64_t location;
    uint64_t length;
    qvm_state_types_t qst_type;
    qvm_state_flags_t qst_flags;
    uint32_t spare;
};

Data:

uint64_t location

The exact meaning of this field depends on the type field.

It is generally understood as an offset into the object implied by type. For instance, if it is QST_CPUREGS, location is the offset of a field that contains the value for a specific register in a CPU-dependent context structure.

This mechanism allows for writing type-agnostic code when managing data movement.

uint64_t length
The length of the data element, in bytes; not all lengths are valid for all types.
qvm_state_types_t qst_type
A bitset of values from qvm_state_types_t.
qvm_state_flags_t qst_flags
A bitset of values from qvm_state_flags_t.
uint32_t spare
Reserved; set to 0.
