AttemptLockDosList -- Attempt to lock the Dos Lists for use (V36)
dlist = AttemptLockDosList(flags)
D0 D1
struct DosList *AttemptLockDosList(ULONG)
Locks the dos device list in preparation to walk the list. If the
list is 'busy' then this routine will return NULL. See LockDosList()
for more information.
flags - Flags stating which types of nodes you want to lock.
dlist - Pointer to the beginning of the list or NULL. Not a valid
node!
In V36 through V39.23 dos, this would return NULL or 0x00000001 for
failure. Fixed in V39.24 dos (after kickstart 39.106).
