+.SH DESCRIPTION
+.IX Header "DESCRIPTION"
+\&\fBCMS_data_create_ex()\fR creates a \fBCMS_ContentInfo\fR structure
+with a type \fBNID_pkcs7_data\fR. The data is supplied via the \fIin\fR BIO.
+The library context \fIlibctx\fR and the property query \fIpropq\fR are used when
+retrieving algorithms from providers. The \fIflags\fR field supports the
+\&\fBCMS_STREAM\fR flag. Internally \fBCMS_final()\fR is called unless \fBCMS_STREAM\fR is
+specified.
+.PP
+The \fBCMS_ContentInfo\fR structure can be freed using \fBCMS_ContentInfo_free\fR\|(3).
+.PP
+\&\fBCMS_data_create()\fR is similar to \fBCMS_data_create_ex()\fR
+but uses default values of NULL for the library context \fIlibctx\fR and the
+property query \fIpropq\fR.
+.SH "RETURN VALUES"
+.IX Header "RETURN VALUES"
+If the allocation fails, \fBCMS_data_create_ex()\fR and \fBCMS_data_create()\fR
+return NULL and set an error code that can be obtained by \fBERR_get_error\fR\|(3).
+Otherwise they return a pointer to the newly allocated structure.

+.SH HISTORY
+.IX Header "HISTORY"
+The \fBCMS_data_create_ex()\fR method was added in OpenSSL 3.0.
