char **cmds;
if (strchr(input, '|'))
cmds = split(input,'|');

I call strdup to duplicate the 'card' string in set_device( devname )
set_device( devname )
and then I use 'card' to open mixer:
devname is in format hw:0/Mic
static char *card, *channel;
static snd_mixer_t *handle = NULL;
static snd_mixer_elem_t…
My main intention is to pass a pointer to a structure, to a function, which will allocate memory and fill all its values. After returning back i will print it on screen.
Structure looks like this.
