The hash key is not copied so we can't change the string from:
modname/modalias
to:
modname'\0'modalias
in order to setup mod->name and mod->alias.
Now what we do is:
1) if name is in the form 'modname/modalias', the final struct
kmod_module will be:
struct kmod_module {
char *alias;------,
char *name;-----, |
char *hashkey;--|-|-,
} | | |
name <------------------' | |
alias <-------------------' |
hashkey <-------------------'
2) if name is in the simple form 'modname', then the final struct
kmod_module will be:
struct kmod_module {
char *alias;------> NULL
char *name;-----,
char *hashkey;--|---,
} | |
name <------------------*---'

libkmod - linux kernel module handling library
ABSTRACT
========
libkmod was created to allow programs to easily insert, remove and
list modules, also checking its properties, dependencies and aliases.
there is no shared/global context information and it can be used by
multiple sites on a single program, also being able to be used from
threads, although it's not thread safe (you must lock explicitly).
OVERVIEW
========
Every user should create and manage it's own library context with:
struct kmod_ctx *ctx = kmod_new(kernel_dirname);
kmod_unref(ctx);
Modules can be created with by various means:
struct kmod_module *mod;
int err;
err = kmod_module_new_from_path(ctx, path, &mod);
if (err < 0) {
/* code */
} else {
/* code */
kmod_module_unref(mod);
}
err = kmod_module_new_from_name(ctx, name, &mod);
if (err < 0) {
/* code */
} else {
/* code */
kmod_module_unref(mod);
}
Or could be resolved from a known alias to a list of alternatives:
struct kmod_list *list, *itr;
int err;
err = kmod_module_new_from_lookup(ctx, alias, &list);
if (err < 0) {
/* code */
} else {
kmod_list_foreach(itr, list) {
struct kmod_module *mod = kmod_module_get_module(itr);
/* code */
}
}
