Example

#include "pn_api_iod_dbai.h"
 
PN_API_IOD_Handle_t* pnHandle = NULL;
PN_API_IOD_BufferLock_t lock;
uint32_t status;
 
pnHandle = PN_API_IOD_new();
 
PN_API_IOD_enterDbai();
//Fill up lock
 
status = PN_API_IOD_lockDbaiBuf(pnHandle, lock);
 
//do work
 
status = PN_API_IOD_unlockDbaiBuf(pnHandle, lock);
status = PN_API_IOD_exitDbai(pnHandle);
