get_kernel_syms - retrieve exported kernel and module symbols
SYNOPSIS
#include <linux/module.h>
int get_kernel_syms(struct kernel_sym *table);
DESCRIPTION
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.
RETURN VALUE
Returns the number of symbols copied to
table. There is no possible error return.
CONFORMING TO
get_kernel_syms() is Linux specific.
BUGS
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).
NOTES
This system call is only present on Linux up until kernel 2.4;
it was removed in Linux 2.6.
