So the goal of Libasyncd project is 14 | to make a flexible and fast asynchronous server framework with nice abstraction that 15 | can cut down the complexity. 16 | 17 | ## Why libasyncd? 18 | 19 | libasyncd is a light-weight single-threaded asynchronous RPC server. It is efficient 20 | especially when server needs to handle a large number of concurrent connections where 21 | connection-per-thread or connection-per-process model is not appropriate to consider. 22 | 23 | * Stands as a generic event-based server library. (single-thread) 24 | * Embeddable library module - you write main(). 25 | * Pluggable protocol handlers. 26 | * Complete HTTP protocol handler. (support chunked transfer-encoding) 27 | * Support request pipelining. 28 | * Support multiple hooks. 29 | * Support SSL - Just flip the switch on. 30 | * Support IPv4, IPv6 and Unix Socket. 31 | * Simple to use - Check out examples. 32 | 33 | ## Compile & Install. 34 | ``` 35 | $ git clone https://github.com/wolkykim/libasyncd 36 | $ cd libasyncd 37 | $ ./configure 38 | # If using system wide install of qlibc, add QLIBC=system to make install command 39 | $ make install 40 | ``` 41 | 42 | ## API Reference 43 | 44 | * [libasyncd API reference](http://wolkykim.github.io/libasyncd/doc/html/globals_func.html) 45 | 46 | ## "Hello World", Asynchronous Socket Server example. 47 | ```c 48 | int my_conn_handler(short event, ad_conn_t *conn, void *userdata) { 49 | if (event & AD_EVENT_WRITE) { 50 | evbuffer_add_printf(conn->out, "Hello World."); 51 | return AD_CLOSE; 52 | } 53 | return AD_OK; 54 | } 55 | 56 | int main(int argc, char **argv) { 57 | ad_log_level(AD_LOG_DEBUG); 58 | ad_server_t *server = ad_server_new(); 59 | ad_server_set_option(server, "server.port", "2222"); 60 | ad_server_register_hook(server, my_conn_handler, NULL); 61 | return ad_server_start(server); 62 | } 63 | ``` 64 | 65 | ## "Hello World", Asynchronous HTTPS Server example. 66 | ```c 67 | int my_http_get_handler(short event, ad_conn_t *conn, void *userdata) { 68 | if (event & AD_EVENT_READ) { 69 | if (ad_http_get_status(conn) == AD_HTTP_REQ_DONE) { 70 | ad_http_response(conn, 200, "text/html", "Hello World", 11); 71 | return ad_http_is_keepalive_request(conn) ?
