Description

In OpenSSL docs there are described SSL_CTX_clear_mode and SSL_CTX_get_mode functions.

It seems that library rust-openssl does not expose those functions. Is it possible to create bindings for them or other/newer functions should be used instead?

I see that https://docs.rs/openssl-sys/0.9.104/src/openssl_sys/ssl.rs.html#245-247 even SSL_CTX_set_mode does not use underlying OpenSSL's provided SSL_CTX_set_mode.

pub unsafe fn SSL_CTX_set_mode(ctx: *mut SSL_CTX, op: c_long) -> c_long {
    SSL_CTX_ctrl(ctx, SSL_CTRL_MODE, op, ptr::null_mut())
}

It SSL_CTX_ctrl docs there is comment:

These functions should never be called directly.

Research direction

Start with the openssl_sys ssl.rs definitions around SSL_CTX_set_mode and compare them with the linked OpenSSL documentation for SSL_CTX_clear_mode and SSL_CTX_get_mode. Determine how these functions should be exposed alongside the existing binding; done means the requested functions are available without relying on direct SSL_CTX_ctrl calls.
