I use openssl with TCP and TCP/TLS connection. I send a message to server and than I wait for response on select() function. I know, that sometimes I try to read, when there are no data on SSL buffer. I thought, that I must use the BIO_set_nbio to activate the non-blocking I/O operation, because, if I dont do it, then when I call the read function, it blocks and it will wait until there will be some data in SSL buffer to read. But for some testing, I remove the BIO_set_nbio function, and it still works. When I call BIO_read, it returns with some error code and it doesnt wait for data. So it seems its still nonblocking.
I´m confused with this. Can somebody explain me this? ______________________________________________________________________ OpenSSL Project http://www.openssl.org User Support Mailing List openssl-users@openssl.org Automated List Manager [EMAIL PROTECTED]
