c++ - Program exits on SSL_connect -

i'm having problem program i'm working on shut down after call ssl_connect(). can't error code ever, since calling ssl_get_error() afterwards ignored since exits program. if normal http request connect() works fine. have ideas on this?

i'm running on raspberry pi 3 raspbian. i'm new ssl, pointers appreciated.

edit: here's code snippet of i'm trying do

#include <openssl/ssl.h> #include <iostream> #include <resolv.h> #include <sys/socket.h> #include <sys/types.h> #include <netdb.h> #include <arpa/inet.h> #include <string> #include <unistd.h>  int main() {         int sockfd;         struct addrinfo hints, *servinfo, *p;         int rv;          memset(&hints, 0, sizeof hints);         hints.ai_family = af_unspec;         hints.ai_socktype = sock_stream;          if ((rv = getaddrinfo("www.example.com", "https", &hints, &servinfo)) != 0)         {             fprintf(stderr, "getaddrinfo : %s\n", gai_strerror(rv));             exit(1);         }          ssl_load_error_strings();         ssl_library_init();         ssl_ctx = ssl_ctx_new(sslv23_client_method());          ssl * connection = ssl_new(int sockfd;         struct addrinfo hints, *servinfo, *p;         int rv;          memset(&hints, 0, sizeof hints);         hints.ai_family = af_unspec;         hints.ai_socktype = sock_stream;          if ((rv = getaddrinfo("www.example.com", "https", &hints, &servinfo)) != 0)         {             fprintf(stderr, "getaddrinfo : %s\n", gai_strerror(rv));             exit(1);         }          ssl_load_error_strings();         ssl_library_init();         ssl_ctx = ssl_ctx_new(sslv23_client_method());          ssl * connection = ssl_new(ssl_ctx);          (p = servinfo; p != null; p = p->ai_next)         {             if ((sockfd = socket(p->ai_family, p->ai_socktype,                 p->ai_protocol)) == -1)                  {                     perror("socket");                     continue;                 }             int fd = ssl_set_fd(connection, sockfd);                  break;         }          if (p == null)          {             // looped off end of list no connection             fprintf(stderr, "failed connect\n");             exit(2);         }         int connret = 0;         while(connret != 1 )         {             connret = ssl_connect(connection);             cout << "error : " << ssl_get_error(connection, connret) << endl;          }            freeaddrinfo(servinfo); return 0; } 

edit 2 : managed run through debugger, i'm getting :

(program exited code: 141) press return continue

which according question : socket connection getting closed abruptly code 141 sigpipe signal.

unsure why caused crash, ssl_connect not equivalent of connect: initiates tls/ssl handshake on already established connection. sockfd not connected in code, fails , sets connret -1 causing endless loop.

you should connect socket after creation , before initiating ssl handshake:

    if ((sockfd = socket(p->ai_family, p->ai_socktype,         p->ai_protocol)) == -1)      {         perror("socket");         continue;     }     /* connect @ tcp level */     if (connect(sockfd, servinfo->ai_addr, servinfo->ai_addrlen)) {         perror("connect");         continue;     }     int fd = ssl_set_fd(connection, sockfd);     ... 

but anyway, should control program remove possible endless loops, , consistent in error messages: either use c++ stream cout or c file* stderr. , better close socket if opened.
