Detailed Description

This opaque object represents a connection to a MPD server. Call mpd_connection_new() to create a new instance. To free an instance, call mpd_connection_free(). Example:

struct mpd_connection *conn = mpd_connection_new(NULL, 0, 0);

// error handling
if (conn == NULL) {
    fprintf(stderr, "Out of memory\n");
    return;
}
if (mpd_connection_get_error(conn) != MPD_ERROR_SUCCESS) {
    fprintf(stderr, "%s\n", mpd_connection_get_error_message(c));
    mpd_connection_free(c);
    return;
}

// we can now use the connection
mpd_run_next(conn);

// close the connection and free memory
mpd_connection_free(conn);

Error handling: most functions return a bool indicating success or failure. In this case, you may query the nature of the error with the functions mpd_connection_get_error(), mpd_connection_get_error_message(), mpd_connection_get_server_error().

Some errors can be cleared by calling mpd_connection_clear_error(), like MPD_ERROR_SERVER, MPD_ERROR_ARGUMENT. Most others are fatal, and cannot be recovered, like MPD_ERROR_CLOSED - mpd_connection_clear_error() returns false.

Some functions like mpd_recv_pair() cannot differentiate between "end of response" and "error". If this function returns NULL, you have to check mpd_connection_get_error().

To integrate this object in a non-blocking event I/O loop, use mpd_connection_get_fd() to obtain the underlying socket descriptor.
