PulseAudio Rust language linking library for the ‘simple’ component. //! //! This crate is a *sys* type crate targetting the PulseAudio (“simple” interface) C API. As a //! *sys* type crate it does nothing more than simply describe the C API in Rust form. Please be //! aware that there is a “higher level” *binding* crate available (`libpulse-simple-binding`) built //! on top of this, which you will most likely prefer to use instead. //! //! Virtually no documentation is provided here, since it is pointless to duplicate it here from the //! C header files, considering that most users will be using the binding crate (which is heavily //! documented). #![doc(html_logo_url = "https://github.com/jnqnfe/pulse-binding-rust/raw/master/logo.png", html_favicon_url = "https://github.com/jnqnfe/pulse-binding-rust/raw/master/favicon.ico")] #![allow(non_camel_case_types, non_snake_case)] extern crate libpulse_sys as pulse; use std::os::raw::{c_char, c_void}; /// An opaque simple connection object. #[repr(C)] pub struct pa_simple { _private: [u8; 0] } #[link(name="pulse-simple")] extern "C" { pub fn pa_simple_new(server: *const c_char, name: *const c_char, dir: pulse::stream::pa_stream_direction_t, dev: *const c_char, stream_name: *const c_char, ss: *const pulse::sample::pa_sample_spec, map: *const pulse::channelmap::pa_channel_map, attr: *const pulse::def::pa_buffer_attr, error: *mut i32) -> *mut pa_simple; pub fn pa_simple_free(s: *mut pa_simple); pub fn pa_simple_write(s: *mut pa_simple, data: *const c_void, bytes: usize, error: *mut i32) -> i32; pub fn pa_simple_drain(s: *mut pa_simple, error: *mut i32) -> i32; pub fn pa_simple_read(s: *mut pa_simple, data: *mut c_void, bytes: usize, error: *mut i32) -> i32; pub fn pa_simple_get_latency(s: *mut pa_simple, error: *mut i32) -> pulse::sample::pa_usec_t; pub fn pa_simple_flush(s: *mut pa_simple, error: *mut i32) -> i32; }
