NAME
snd_card_proc_new - create an info entry for the given card
SYNOPSIS
int snd_card_proc_new (snd_card_t * card, const char * name,
snd_info_entry_t ** 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.
Returns zero if successful, or a negative error code on failure.
