DESCRIPTION

31       The getddent() and getddnam() functions each return a device_deallocate
32       entry.   The   getddent()  function  enumerates  all  device_deallocate
33       entries. Successive calls to this  function  return  either  successive
34       device_deallocate entries or NULL. The getddnam() function searches for
35       a device_deallocate entry with a given device name.
36
37
38       The internal representation of a device_deallocate entry is a  devdeal‐
39       loc_t structure defined in <bsm/devices.h> with the following members:
40
41         char *dd_devname;  /* device allocation name */
42         char *dd_logout;   /* deallocation action on user logout */
43         char *dd_boot;     /* deallocation action on system boot */
44
45
46
47       The  setddent()  function "rewinds" to the beginning of the enumeration
48       of device_deallocate entries. Calls to getddnam() may leave the enumer‐
49       ation  in an indeterminate state, so setddent() should be called before
50       the first call to getddent().
51
52
53       The endddent() function can be called to indicate  that  device_deallo‐
54       cate  processing  is  complete.  The library can then close any opende‐
55       vice_deallocate file, deallocate any internal storage, and so forth.
56
57
58       The setddfile() function changes the pathname used by the  other  func‐
59       tions   for   opening  the  device_deallocate  file,  allowing  use  of
60       device_deallocate  files  other  than  the  default  file,   /etc/secu‐
61       rity/device_deallocate.
62

RETURN VALUES

64       The  getddent() function returns a pointer to a devdealloc_t if it suc‐
65       cessfully enumerates an entry. Otherwise it  returns  NULL,  indicating
66       the end of the enumeration.
67
68
69       The  getddnam() function returns a pointer to a devdealloc_t if it suc‐
70       cessfully locates the requested entry. Otherwise it returns NULL.

NOTES

94       The getddent() and getddnam() functions allocate memory for the  point‐
95       ers they return. This memory can be deallocated with the free(3C) func‐
96       tion.
