SYNOPSIS
#include <openssl/x509.h>
STACK_OF(X509_ATTRIBUTE) *
X509at_add1_attr(STACK_OF(X509_ATTRIBUTE)
**pattrs, X509_ATTRIBUTE *attr);

*data, int len);

X509at_add1_attr_by_NID(STACK_OF(X509_ATTRIBUTE)
**pattrs, int nid, int
type, const unsigned char *data,
int len);
STACK_OF(X509_ATTRIBUTE) *
X509at_add1_attr_by_txt(STACK_OF(X509_ATTRIBUTE)
**pattrs, const char *name, int
type, const unsigned char *data,

X509at_delete_attr(STACK_OF(X509_ATTRIBUTE)
*attrs, int index);
DESCRIPTION
X509at_add1_attr() appends a deep copy of
attr to the end of **pattrs. If
*pattrs is NULL, a new array is
allocated, and in case of success, a pointer to it is assigned to
*pattrs.
X509at_add1_attr_by_OBJ(),
X509at_add1_attr_by_NID(), and
X509at_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, and append it to **pattrs using
X509at_add1_attr().
X509at_delete_attr() deletes the element
with the zero-based index from the array
*attrs.
RETURN VALUES
X509at_add1_attr(),
X509at_add1_attr_by_OBJ(),
X509at_add1_attr_by_NID(), and
X509at_add1_attr_by_txt() return a pointer to the
modified or new array or NULL if the
pattrs argument is NULL or if
creating or copying the X.501 Attribute object or memory allocation fails.
X509at_delete_attr() returns the deleted
element or NULL if attrs is
NULL or if the requested index
is negative or greater than or equal to the number of objects in
*attrs.
