DESCRIPTION
These functions support associating an array of X.501 Attributes with a PKCS#10 certification request.
X509_REQ_add1_attr()
appends a deep copy of the attr, allocating a new
array if necessary.
X509_REQ_add1_attr_by_OBJ(),
X509_REQ_add1_attr_by_NID(),
and
X509_REQ_add1_attr_by_txt()
create a new X.501 Attribute object using
X509_ATTRIBUTE_create_by_OBJ(3),
X509_ATTRIBUTE_create_by_NID(3), or
X509_ATTRIBUTE_create_by_txt(3), respectively, allocating a
new array if necessary.
X509_REQ_delete_attr()
deletes the attribute with the zero-based index.
X509_REQ_get_attr()
returns the attribute with the zero-based index.
X509_REQ_get_attr_count()
returns the number of attributes currently associated with
req.
X509_REQ_get_attr_by_OBJ()
and
X509_REQ_get_attr_by_NID()
search for an attribute of the type obj or
nid.
RETURN VALUES
X509_REQ_add1_attr(),
X509_REQ_add1_attr_by_OBJ(),
X509_REQ_add1_attr_by_NID(), and
X509_REQ_add1_attr_by_txt() return 1 for success or
0 for failure.
X509_REQ_delete_attr() and
X509_REQ_get_attr() return the deleted or requested
attribute or NULL if the requested index is negative
or greater than or equal to the current number of attributes associated with
req.
X509_REQ_get_attr_count() returns the
current number of attributes.
X509_REQ_get_attr_by_OBJ() and
X509_REQ_get_attr_by_NID() return the index of the
first attribute that has an index greater than
start_after and a type matching
obj or nid, respectively, or -1
on failure. In addition, X509_REQ_get_attr_by_NID()
returns -2 if OBJ_nid2obj(3) fails on the requested
nid.
