NAME
       X509_ACERT_add1_attr, X509_ACERT_add1_attr_by_NID,
       X509_ACERT_add1_attr_by_OBJ, X509_ACERT_add1_attr_by_txt,
       X509_ACERT_delete_attr - X509_ACERT attribute functions

SYNOPSIS
        #include <openssl/x509_acert.h>

        int X509_ACERT_add1_attr(X509_ACERT *x, X509_ATTRIBUTE *attr);
        int X509_ACERT_add1_attr_by_NID(X509_ACERT *x, int nid, int type,
                                        const void *bytes, int len);
        int X509_ACERT_add1_attr_by_OBJ(X509_ACERT *x, const ASN1_OBJECT *obj,
                                        int type, const void *bytes, int len);
        int X509_ACERT_add1_attr_by_txt(X509_ACERT *x, const char *attrname, int type,
                                        const unsigned char *bytes, int len);
        X509_ATTRIBUTE *X509_ACERT_delete_attr(X509_ACERT *x, int loc);

DESCRIPTION
       X509_ACERT_add1_attr() adds a constructed X509_ATTRIBUTE attr to the
       existing X509_ACERT structure x.

       X509_ACERT_add1_attr_by_NID() and X509_ACERT_add1_attr_by_OBJ() add an
       attribute of type nid or obj with a value of ASN1 type type constructed
       using len bytes from bytes.

       X509_ACERT_add1_attr_by_txt() adds an attribute of type attrname with a
       value of ASN1 type type constructed using len bytes from bytes.

       X509_ACERT_delete_attr() will delete the locth attribute from x and
       return a pointer to it or NULL if there are fewer than loc attributes
       contained in x.

RETURN VALUES
       X509_ACERT_add1_attr(), X509_ACERT_add1_attr_by_NID(), and
       X509_ACERT_add1_attr_by_OBJ() return 1 for success and 0 for failure.

       X509_ACERT_delete_attr() returns a X509_ATTRIBUTE pointer on success or
       NULL on failure.
