The [memflow](https://github.com/memflow/memflow) FFI crate provides an interface to the memflow API for C/C++. Currently a single `memflow.h` file is generated aside from the dynamic library that can be used to interact with memflow.
|
||
|
|
|
||
|
|
A simple example that initializes the library:
|
||
|
|
```cpp
|
||
|
|
#include "memflow.h"
|
||
|
|
#include <stdio.h>
|
||
|
|
|
||
|
|
int main(int argc, char *argv[]) {
|
||
|
|
log_init(4);
|
||
|
|
|
||
|
|
ConnectorInventory *inv = inventory_try_new();
|
||
|
|
printf("inv: %p\n", inv);
|
||
|
|
|
||
|
|
const char *conn_name = argc > 1? argv[1]: "kvm";
|
||
|
|
const char *conn_arg = argc > 2? argv[2]: "";
|
||
|
|
|
||
|
|
CloneablePhysicalMemoryObj *conn =
|
||
|
|
inventory_create_connector(inv, conn_name, conn_arg);
|
||
|
|
printf("conn: %p\n", conn);
|
||
|
|
|
||
|
|
if (conn) {
|
||
|
|
PhysicalMemoryObj *phys_mem = downcast_cloneable(conn);
|
||
|
|
printf("phys_mem: %p\n", phys_mem);
|
||
|
|
|
||
|
|
uint64_t read = phys_read_u64(phys_mem, addr_to_paddr(0x30000));
|
||
|
|
|
||
|
|
printf("Read: %lx\n", read);
|
||
|
|
|
||
|
|
phys_free(phys_mem);
|
||
|
|
|
||
|
|
connector_free(conn);
|
||
|
|
printf("conn freed!\n");
|
||
|
|
}
|
||
|
|
|
||
|
|
inventory_free(inv);
|
||
|
|
printf("inv freed!\n");
|
||
|
|
|
||
|
|
return 0;
|
||
|
|
}
|
||
|
|
```
