SSL_get_fd(3) OpenSSL SSL_get_fd(3) NAME SSL_get_fd - get file(1,n) descriptor linked to an SSL object SYNOPSIS #include <openssl/ssl.h> int SSL_get_fd(SSL *ssl); int SSL_get_rfd(SSL *ssl); int SSL_get_wfd(SSL *ssl); DESCRIPTION SSL_get_fd() returns the file(1,n) descriptor which is linked to ssl. SSL_get_rfd() and SSL_get_wfd() return the file(1,n) descriptors for the read(2,n,1 builtins) or the write(1,2) channel, which can be different. If the read(2,n,1 builtins) and the write(1,2) channel are different, SSL_get_fd() will return the file(1,n) descrip- tor of the read(2,n,1 builtins) channel. RETURN VALUES The following return values can occur: -1 The operation failed, because the underlying BIO is not of the cor- rect type (suitable for file(1,n) descriptors). >=0 The file(1,n) descriptor linked to ssl.
