end

- (Hash) CollectOptions(modname)

this function converts options for modules from 'modules_conf' data structure to another - it is needed for writing options to /etc/modules conf. eg. we have these configured cards: [ $[“model”: “sblive”, “module”:“snd-emu10k1”, “options” :$[“opt1”: “a”, “opt2”: “b”]], $[“model”: “sblive”, “module”:“snd-emu10k1”, “options”: $[“opt2”: “c”]], $[“model”: “other”, “module”:“mod2”, “options”: $[“opt1”: “a”, “opt2”: “b”]] ] CollectOptions (“snd-emu10k1”) returns $[“opt1”:“a,”, “opt2”:“b,c”]

Parameters:

  • modname (String)

    module name

Returns:

  • (Hash)

    Map with collected options
