.Fn X509_REQ_INFO_free "X509_REQ_INFO *req_info"
.Sh DESCRIPTION
.Fn X509_REQ_new
allocates and initializes an empty
.Vt X509_REQ
object, representing an ASN.1
.Vt CertificationRequest
structure defined in RFC 2986 section 4.2.
It can hold a pointer to an
.Vt X509_REQ_INFO
object discussed below together with a cryptographic signature and
information about the signature algorithm used.
.Fn X509_REQ_free
frees
.Fa req .
If
.Fa req
is a
.Dv NULL
pointer, no action occurs.
.Pp
.Fn X509_REQ_INFO_new
allocates and initializes an empty
.Vt X509_REQ_INFO
object, representing an ASN.1
.Vt CertificationRequestInfo
structure defined in RFC 2986 section 4.1.
It is used inside the
.Vt X509_REQ
object and can hold the subject and the public key of the requested
certificate and additional attributes.
.Fn X509_REQ_INFO_free
frees
.Fa req_info .
If
.Fa req_info
is a
.Dv NULL
pointer, no action occurs.
.Sh RETURN VALUES
.Fn X509_REQ_new
and
.Fn X509_REQ_INFO_new
return the new
.Vt X509_REQ
or
.Vt X509_REQ_INFO
object, respectively, or
.Dv NULL
if an error occurs.
