44 These functions facilitate loading kernel modules from userland
49 function takes a name and returns a non-zero value if a module of that
50 name is currently loaded.
51 The name can be either the name of a module file
53 the same name without the
57 or the name of a module contained within that file
59 Only the latter will return correct results if the module is compiled
64 function is a simple wrapper around the
67 It returns zero if and only if the corresponding
69 call succeeded or returned
