get_kernel_syms — retrieve exported kernel and module symbols
#include <linux/module.h>
int
get_kernel_syms( |
struct kernel_sym * | table) ; |
If table
is NULL,
get_kernel_syms
() returns the
number of symbols available for query. Otherwise it fills in
a table of structures:
struct kernel_sym { }; unsigned long value
;char name
[60];
The symbols are interspersed with magic symbols of the
form #module-name
with the kernel having an empty name. The value associated
with a symbol of this form is the address at which the module
is loaded.
The symbols exported from each module follow their magic module tag and the modules are returned in the reverse of the order in which they were loaded.
There is no way to indicate the size of the buffer
allocated for table
.
If symbols have been added to the kernel since the program
queried for the symbol table size, memory will be
corrupted.
The length of exported symbol names is limited to 59 characters.
Because of these limitations, this system call is deprecated in favor of query_module(2) (which is itself nowadays deprecated in favor of other interfaces described on its manual page).
