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.

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.
