Macro Description:
|
||
|
|
|
||
|
|
This macro is used to test that a LoadLibrary call succeeded.
|
||
|
|
|
||
|
|
Arguments:
|
||
|
|
|
||
|
|
hModule - the handle returned from the LoadLibrary call.
|
||
|
|
|
||
|
|
Notes:
|
||
|
|
|
||
|
|
Win31 documentation says that errors are less than HINSTANCE_ERROR
|
||
|
|
and that success is greater than 32. Since HINSTANCE_ERROR is 32,
|
||
|
|
this leaves the value of 32 as being undefined!

Macro Description:
|
||
|
|
|
||
|
|
This macro is used to determine if a buffer passed in has valid
|
||
|
|
addresses and writeable memory.
|
||
|
|
|
||
|
|
Arguments:
|
||
|
|
|
||
|
|
lpBuffer - the address of the buffer.
|
||
|
|
|
||
|
|
lpcbBuffer - the address of a DWORD containing the size of the
|
||
|
|
buffer that is filled in on return with the
|
||
|
|
required size of the buffer if the buffer
|
||
|
|
is not large enough.
|
||
|
|
|
||
|
|
Evalutes to:
|
||
|
|
|
||
|
|
An expression that returns TRUE or FALSE.
|
||
|
|
|
||
|
|
Notes:
|
||
|
|
|
||
|
|
Only valid for Win32 applications to call.
|
||
|
|
The macro does weak validation as it is used generically in many APIs.
|
||
|
|
In particular, this means that the macro succeeds a NULL lpcbBuffer,
|
||
|
|
and zero *lpcbBuffer. In neither of these cases does it validate
|
||
|
|
that lpBuffer is a valid address (and relies upon the behavior of
|
||
|
|
IsBadWritePtr when *lpcbBuffer is zero).
