System-wide system calls

This section covers system calls, which can not be assigned to any other sections. Such system calls usually provide system wide information about kernel and whole operation system. Also they can change typical behavior of Linux and extend its functionality by loadable modules.


Tip: For detailed information about each system call please read: Linux man pages

Loadable modules

CREATE_MODULE174Create a loadable module entry
INIT_MODULE175Load a kernel module
FINIT_MODULE313Load a kernel module
DELETE_MODULE176Unload a kernel module
QUERY_MODULE178Query the kernel for various bits pertaining to modules
GET_KERNEL_SYMS177Retrieve exported kernel and module symbols
