GET_KERNEL_SYMS(2) Linux Module Support GET_KERNEL_SYMS(2)
NAME
get_kernel_syms - retrieve exported kernel and module sym-
bols
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
order they were loaded.
RETURN VALUE
Returns the number of symbols returned. There is no pos-
sible error return.
SEE ALSO
create_module(2), init_module(2), delete_module(2),
query_module(2).
BUGS
There is no way to indicate the size of the buffer allo-
cated for table. If symbols have been added to the kernel
since the program queried for the symbol table size, mem-
ory will be corrupted.
The length of exported symbol names is limited to 59.
Because of these limitations, this system call is depreci-
ated in favor of query_module.
