SSL_set_fd(3) OpenSSL SSL_set_fd(3) NAME SSL_set_fd - connect the SSL object with a file(1,n) descriptor SYNOPSIS #include <openssl/ssl.h> int SSL_set_fd(SSL *ssl, int fd); int SSL_set_rfd(SSL *ssl, int fd); int SSL_set_wfd(SSL *ssl, int fd); DESCRIPTION SSL_set_fd() sets the file(1,n) descriptor fd as the input/output facility for the TLS/SSL (encrypted) side of ssl. fd will typically be the socket(2,7,n) file(1,n) descriptor of a network connection. When performing the operation, a socket(2,7,n) BIO is automatically created to interface between the ssl and fd. The BIO and hence the SSL engine inherit the behaviour of fd. If fd is non-blocking, the ssl will also have non-blocking behaviour. If there was already a BIO connected to ssl, BIO_free() will be called (for both the reading and writing side, if(3,n) different). SSL_set_rfd() and SSL_set_wfd() perform the respective action, but only for the read(2,n,1 builtins) channel or the write(1,2) channel, which can be set(7,n,1 builtins) indepen- dently. RETURN VALUES The following return values can occur: 0 The operation failed. Check the error(8,n) stack to find out why. 1 The operation succeeded.
