+=head1 NAME
+
+ i2d_CMS_bio_stream - output CMS_ContentInfo structure in BER format.
+
+=head1 SYNOPSIS
+
+ #include <openssl/cms.h>
+
+ int i2d_CMS_bio_stream(BIO *out, CMS_ContentInfo *cms, BIO *data, int flags);
+
+=head1 DESCRIPTION
+
+i2d_CMS_bio_stream() outputs a CMS_ContentInfo structure in BER format.
+
+It is otherwise identical to the function SMIME_write_CMS().
+
+=head1 NOTES
+
+This function is effectively a version of the i2d_CMS_bio() supporting
+streaming.
+
+=head1 BUGS
+
+The prefix "i2d" is arguably wrong because the function outputs BER format.
+
+=head1 RETURN VALUES
+
+i2d_CMS_bio_stream() returns 1 for success or 0 for failure.
