Docu:: Alsa Audio API:: A minimal capture program

[Torsten Mohr <tmohr@s.netic.de>]

Hi,

i copied the "minimal capture program" from the
Alsa page -> Documentation -> Tutorial on using the
ALSA Audio API -> A minimal capture program.

I added "int rate = 44100" and changed the wrong
parameter "44100" in "snd_pcm_hw_params_set_rate_near"
to "&rate".

bash# gcc capture.c -lasound
bash# a.out default

But if i add a "sleep(1)" in the "for(i = 0; i < 10; i++)",
the whole program crashes.


I want to write a program where some chunk of
data is sampled from time to time, with some delay
inbetween.  The behaviour above (with sleep(1))
is a good example for what i want to do.

Can anybody tell me what i need to change to make
the program work ok?


Thanks for any hints,
Torsten.
