func or pFunc in tests ?

[GOUJON Alexandre]

Hi,

I'm planning to add a test in the wine test suite and I noticed a 
difference.

Some tests call directly the function by its name (i.e. 
GetWindowsDirectory, CreateFileA, CloseHandle...) while others declare a 
pointer to the function (prefixing its name by 'p' and followed by a 
capital letter) retrieved via GetProcAddress.

I know that tests have been written by lots of different people at 
different times and the general rule is "follow the style of the test 
file to be consistent" but here, both styles exist in the same file 
(kernel32/tests/volume.c).

Is there any rule concerning using func over pFunc ?
Is it related to the module it comes from ?

Thanks
