This looks fine other than the fact that you didn't put comments in
there like the existing flags. Those are for doxygen, I think. The
mapping happens in the openFunc on these lines:
// translate open flags
for (int i = 0; i < OS::NUM_OPEN_FLAGS; i++) {
if (tgtFlags & OS::openFlagTable[i].tgtFlag) {
tgtFlags &= ~OS::openFlagTable[i].tgtFlag;
hostFlags |= OS::openFlagTable[i].hostFlag;
}
}
That's referencing the mapping set up in, for example,
src/arch/x86/linux/linux.cc.
