mongoc_socket_recv (mongoc_socket_t *sock,
                    void *buf,
                    size_t buflen,
                    int flags,
                    int64_t expire_at);

Parameters#

  • sock: A mongoc_socket_t.

  • buf: A buffer to read into.

  • buflen: A size_t with the number of bytes to receive.

  • flags: flags for recv().

  • expire_at: A int64_t with the time to expire in monotonic time using System Clock, which is in microseconds.
