For any given certificate chain use either one or the other, but
in many cases SSL_CTX_use_certificate_chain_file() is the more
convenient choice.

    ERR_clear_error();
    if (SSL_CTX_use_certificate_chain_file(ctx, cert_file) <= 0) {
	/* Handle error */
    }
    if (SSL_CTX_use_PrivateKey_file(ctx, key_file, SSL_FILETYPE_PEM) <= 0) {
	/* Handle error */
    }
    if (!SSL_CTX_check_private_key(ctx)) {
	/* Handle error */
    }
    /* Success */

See the SSL_CTX_use_certificate(3) manpage for a more detailed
description.
