address name [defining module]
The describing header can be turned off with the option '-h'.
Normally, only the symbols defined by the loaded modules are show, but with the option '-a', all exported symbols can be seen.
The information can also be seen in /proc/ksyms. A shell-script version 'ksyms.sh' can be used to get the information from '/proc/ksyms' instead, but this program gets the symbol information directly from the kernel with a system call.
With the option '-m' (stands for memory map), you can also see the starting address and the size of the allocated memory for every loaded module.
