NAMEget_kernel_syms - retrieve exported kernel and module symbols
#include <linux/module.h> int get_kernel_syms(struct kernel_sym *table);
DESCRIPTIONIf table is NULL, get_kernel_syms returns the number of symbols available for query. Otherwise it fills in a table of structures:
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.
RETURN VALUEReturns the number of symbols returned. There is no possible error return.
SEE ALSOcreate_module(2), init_module(2), delete_module(2), query_module(2).
BUGSThere 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.
Because of these limitations, this system call is deprecated in favor of query_module.
