[Freeswitch-dev] SSL_read in do_dtls() question

Hi, Just curious, why use SSL_read in do_dtls() [1] while in the same time Freeswitch use BIO_write. Just wondering why not use BIO_read. I replaced SSL_read with BIO_read and it is working fine with chrome for few calls. Not intensive test actually. So, the line become if (BIO_read(dtls->write_bio, dtls->data, dtls->bytes) == (int)dtls->bytes) Another question, still in do_dtls() about this line: BIO_write(dtls->read_bio, dtls->data, dtls->bytes) Why use dtls->read_bio in write operation? Why also need dtls->write_bio in my BIO_read above. It seems weird for me [1]https://github.com/FreeSWITCH/FreeSWITCH/blob/master/src/switch_rtp.c#L2376 -- Iwan Budi Kusnanto
