!!DESCRIPTION |
|
|
21 |
|
|
|
22 |
|
|
|
23 |
If ''table'' is __NULL__, __get_kernel_syms__ |
|
|
24 |
returns the number of symbols available for query. Otherwise |
|
|
25 |
it fills in a table of structures: |
|
|
26 |
|
|
|
27 |
|
|
|
28 |
struct kernel_sym |
|
|
29 |
{ |
|
|
30 |
unsigned long value; |
|
|
31 |
char name[[60]; |
|
|
32 |
}; |
|
|
33 |
|
|
|
34 |
|
|
|
35 |
The symbols are interspersed with magic symbols of the form |
|
|
36 |
__#__''module-name'' with the kernel having an empty |
|
|
37 |
name. The value associated with a symbol of this form is the |
|
|
38 |
address at which the module is loaded. |
|
|
39 |
|
|
|
40 |
|
|
|
41 |
The symbols exported from each module follow their magic |
|
|
42 |
module tag and the modules are returned in the reverse order |
|
|
43 |
they were loaded. |
|
|
44 |
!!RETURN VALUE |
|
|
45 |
|
|
|
46 |
|
|
|
47 |
Returns the number of symbols returned. There is no possible |
|
|
48 |
error return. |
|
|
49 |

!!BUGS |
|
|
56 |
|
|
|
57 |
|
|
|
58 |
There is no way to indicate the size of the buffer allocated |
|
|
59 |
for ''table''. If symbols have been added to the kernel |
|
|
60 |
since the program queried for the symbol table size, memory |
|
|
61 |
will be corrupted. |
|
|
62 |
|
|
|
63 |
|
|
|
64 |
The length of exported symbol names is limited to |
|
|
65 |
59. |
|
|
66 |
|
|
|
67 |
|
|
|
68 |
Because of these limitations, this system call is deprecated |
|
|
69 |
in favor of __query_module__. |
