SND_CARD_PROC_NEW(9)						   Proc Info API					      SND_CARD_PROC_NEW(9)

NAME
       snd_card_proc_new - create an info entry for the given card

SYNOPSIS
       int snd_card_proc_new(struct snd_card * card, const char * name, struct snd_info_entry ** entryp);

ARGUMENTS
       card
	   the card instance

       name
	   the file name

       entryp
	   the pointer to store the new info entry

DESCRIPTION
       Creates a new info entry and assigns it to the given card. Unlike snd_info_create_card_entry, this function registers the info entry as an
       ALSA device component, so that it can be unregistered/released without explicit call. Also, you don't have to register this entry via
       snd_info_register, since this will be registered by snd_card_register automatically.

       The parent is assumed as card->proc_root.

       For releasing this entry, use snd_device_free instead of snd_info_free_entry.

RETURN
       Zero if successful, or a negative error code on failure.
