The classical C program is something like:

int main() { fprintf(stderr, "hello world\n"); }

a classical OpenGL program is:

open up a window
setup ortho view
draw a colored triangle

Now, I want to do the most basic thing for sound in Linux.

I want to:

1) open up speakers
2) send a bunch of data, meant to be interpreted at 40Khz,
3) have pseakers play said data

no midi, no instruments, ... just playing back raw data

What is the easiest way to do this in a C program? [and what libraries; what's the equiv to OpenGL for sound?]

Thanks!
