bitmexcpp's Introduction

BitmexCPP

libwebsockets implementation

This is a simple example of how to connect https://www.bitmex.com using C++

This project has only one dependency https://libwebsockets.org/

if you want to use https://conan.io/ the conanfile.txt is avaiable

ex: with clion

conan install . -s build_type=Debug --install-folder=cmake-build-debug --build missing

You can set different parameters as you need, a full list of parameters can be found here https://libwebsockets.org/lws-api-doc-master/html/structlws__context__creation__info.html

    creation_info.port                     = CONTEXT_PORT_NO_LISTEN;
    creation_info.iface                    = NULL;
    creation_info.protocols                = protocols;
    creation_info.ssl_cert_filepath        = NULL;
    creation_info.ssl_private_key_filepath = NULL;
    creation_info.extensions               = NULL;
    creation_info.gid                      = -1;
    creation_info.uid                      = -1;
    creation_info.options                 |= LWS_SERVER_OPTION_DO_SSL_GLOBAL_INIT;
    creation_info.fd_limit_per_thread      = 1024;
    creation_info.max_http_header_pool     = 1024;
    creation_info.ws_ping_pong_interval    = 10;
    creation_info.ka_time                  = 10;
    creation_info.ka_probes                = 10;
    creation_info.ka_interval              = 10;

Cannot compile

hi @maurodelazeri

I have

add this remote:

{
 "name": "zinnion",
 "url": "http://64.188.48.140/artifactory/api/conan/conan",
 "verify_ssl": false
}

to my ~/.conan/remotes.json, but i get this error:

libwebsockets/3.1.0@zinnion/stable:` Not found in local cache, looking in remotes...
libwebsockets/3.1.0@zinnion/stable: Trying with 'conan-center'...

1. Make sure the remote is reachable or,
2. Disable it by using conan remote disable,
Then try again.

I still cannot compile it on my ubuntu server:
