.Sh DESCRIPTION
.Fn X509_REQ_add_extensions
encodes the array of
.Fa extensions
using
.Xr i2d_X509_EXTENSIONS 3
and adds a new X.501 Attribute object of the type
.Dv NID_ext_req
to
.Fa req
using the equivalent of
.Xr X509_ATTRIBUTE_create_by_NID 3
with a
.Fa type
of
.Dv V_ASN1_SEQUENCE .
.Pp
.Fn X509_REQ_add_extensions_nid
is identical except that the specified
.Fa nid
is used as the X.501 Attribute type instead of
.Dv NID_ext_req .
.Pp
.Fn X509_REQ_get_extensions
retrieves the first value of the first X.501 Attribute of appropriate type.
By default, the attribute types
.Dv NID_ext_req
and
.Dv NID_ms_ext_req
are considered appropriate.
.Pp
.Fn X509_REQ_set_extension_nids
replaces the list of attribute types that
.Fn X509_REQ_get_extensions
considers appropriate for storing extensions.
The
.Fa nids
argument is interpreted as a pointer to the first element
of a variable-sized array of
.Vt int .
The last element of the array has to be
.Dv NID_undef .
The array needs to remain valid until
.Fn X509_REQ_set_extension_nids
is called again with a different argument.
.Pp
.Fn X509_REQ_extension_nid
checks whether
.Fn X509_REQ_get_extensions
regards the
.Fa nid
argument as a type appropriate for storing extensions.
.Sh RETURN VALUES
.Fn X509_REQ_add_extensions
and
.Fn X509_REQ_add_extensions_nid
returns 1 for success or 0 for failure.
.Pp
.Fn X509_REQ_get_extensions
returns a newly allocated array of ASN.1
.Vt Extension
objects or
.Dv NULL
if
.Fa req
is
.Dv NULL ,
does not contain
.Vt CertificationRequestInfo ,
contains no attribute of an appropriate type,
or if decoding or memory allocation fails.
.Pp
.Fn X509_REQ_get_extension_nids
returns the pointer installed with
.Fn X509_REQ_set_extension_nids
or a pointer to a static array
.Brq Dv NID_ext_req , NID_ms_ext_req , NID_undef
by default.
.Pp
.Fn X509_REQ_extension_nid
returns 1 if
.Fa nid
is considered appropriate or 0 otherwise.
