Hello Openssl Developers, Could you please update the documentation on BIO_read, particularly the BIO_read.pod file!?
There is a paragraph in the file: --------------- A 0 or -1 return is not necessarily an indication of an error. In particular when the source/sink is non-blocking or of a certain type it may merely be an indication that no data is currently available and that the application should retry the operation later. --------------- Actually, only -1 indicates that the application should retry the operation later. If during SSL_connect with my implementation of non-blocking sockets BIO_read() returns 0, SSL_connect also returns 0, and the subsequent call of SSL_get_error returns SSL_ERROR_SYSCALL, not SSL_ERROR_WANT_READ. If my implementation of BIO_read() returns -1, SSL_connect also returns -1 and SSL_get_error returns the correct value: SSL_ERROR_WANT_READ. In contrast, you may want to change the source code to match the current documentation. Thank you for cooperation! -- Maxim ______________________________________________________________________ OpenSSL Project http://www.openssl.org Development Mailing List [EMAIL PROTECTED] Automated List Manager [EMAIL PROTECTED] ______________________________________________________________________ OpenSSL Project http://www.openssl.org Development Mailing List [EMAIL PROTECTED] Automated List Manager [EMAIL PROTECTED]
