It should be:

if ((pmode & MSVCRT__S_IREAD) && !(pmode & MSVCRT__S_IWRITE))
    ...;

IMO it would be more convenient to use switch, that would cover
all the possible cases:

switch (pmode & (MSVCRT__S_IREAD | MSVCRT__S_IWRITE))
{
case 0:
...
case MSVCRT__S_IREAD | MSVCRT__S_IWRITE:
...
case MSVCRT__S_IREAD:
...
case MSVCRT__S_IWRITE:
...
}

Of course a test is needed to prove that.
