The FltFreeFileLock routine uninitializes and frees an initialized FILE_LOCK structure.
Syntax
VOID FLTAPI FltFreeFileLock(
[in] PFILE_LOCK FileLock
);
Parameters
[in] FileLock
Pointer to the FILE_LOCK structure. This structure must have been initialized by a previous call to FltAllocateFileLock or FltInitializeFileLock.
Return value
None
Remarks
The FILE_LOCK structure is opaque: that is, its members are reserved for system use.
To allocate and initialize a new file lock structure, call FltAllocateFileLock.
It is a programming error to call FltFreeFileLock for a FILE_LOCK structure that has already been uninitialized by a call to FltUninitializeFileLock.
