// file handle table variables. initially, HandleTable points to
// SmallHandleTable. most processes won't use more than 20 handles.
// if the handle table is full, space in the heap is allocated and the
// SmallHandleTable is copied over.
PFILE_HANDLE HandleTable; // pointer to handle table
ULONG HandleTableLength; // number of entries in handle table
FILE_HANDLE SmallHandleTable[INITIALFILEHANDLES]; // initial handle table
BOOLEAN VerifyFlag; // variable used by DosSet/QueryVerify
// search handle table variables. this size of this table is managed the
// same way as the file handle table, except the table is grown when a search
// handle allocation fails, not when the user specifies it.
PSEARCH_RECORD *SearchHandleTable; // pointer to search handle table
ULONG SearchHandleTableLength; // number of entries in search handle table
PSEARCH_RECORD SmallSearchHandleTable[INITIAL_SEARCH_HANDLES]; // initial search handle table
//
// the client keeps two tables which include information about the current
// directories on the different drives.
// Od2DirHandles holds for each drive a handle to the current directory.
// Od2DirHandlesIsValid holds for each drive a flag indicating whether the
// current directory on it was initialized or not.
