Issue Description
I use C++ to implment the sample code of iep.

    err = NvSciSyncAttrListCreate(syncModule, &cpuWaiterAttrList);
    bool cpuWaiter = true;
    NvSciSyncAttrKeyValuePair keyValue[2];
    memset(keyValue, 0, sizeof(keyValue));
    keyValue[0].attrKey = NvSciSyncAttrKey_NeedCpuAccess;
    keyValue[0].value = (void*) &cpuWaiter;
    keyValue[0].len = sizeof(cpuWaiter);
    NvSciSyncAccessPerm cpuPerm = NvSciSyncAccessPerm_WaitOnly;
    keyValue[1].attrKey = NvSciSyncAttrKey_RequiredPerm;
    keyValue[1].value = (void*) &cpuPerm;
    keyValue[1].len = sizeof(cpuPerm);

    err = NvSciSyncAttrListSetAttrs(cpuWaiterAttrList, keyValue, 2);

I keep getting bad parameter error of the function NvSciSyncAttrListSetAttrs

Dear @rlu1 ,
Could you share the syslog and full error log when encountering error?

I can use the original sample c code. But when I put it in the c++ code there is error.
.cfg is the correct configuration for encoding h264 video. I already tested it with the sample code of iep.

i have checked all the parameters that passed to the NvSciSyncAttrListSetAttrs(). None of them are null.

the error is solved. There are some bytes alignment issue in my codes and the Nvidia’s SDK function cannot interpret them correctly
