Subject: Have BIO_get_conn_int_port use BIO_ctrl instead BIO_int_ctrl
X-Git-Tag: OpenSSL_1_0_1r~23
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=f08360a16072e8bf58fd273eba41cdbc35448cbc;p=oweals%2Fopenssl.git

Have BIO_get_conn_int_port use BIO_ctrl instead BIO_int_ctrl

BIO_int_ctrl isn't made for the purpose BIO_get_conn_int_port used it
for.

This also changes BIO_C_GET_CONNECT to actually return the port
instead of assigning it to a pointer that was never returned back to
the caller.
