       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 avail-
       able for query.  Otherwise it fills in(1,8) a table of structures:

              struct kernel_sym
                unsigned long value;
                char name[60];

       The symbols are interspersed with magic(4,5) 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(4,5) module tag and
       the modules are returned in(1,8) the reverse order they were loaded.

       Returns  the  number  of  symbols returned.  There is no possible error(8,n)

       create_module(2), init_module(2), delete_module(2), query_module(2).

       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.

       Because of these limitations, this system call is deprecated  in(1,8)  favor
       of query_module.
