Function yrs::yxmltext_insert_attr

#[no_mangle]
pub unsafe extern "C" fn yxmltext_insert_attr(
    txt: *const Branch,
    txn: *mut Transaction,
    attr_name: *const c_char,
    attr_value: *const c_char
)

Inserts an XML attribute described using attr_name and attr_value. If another attribute with the same name already existed, its value will be replaced with a provided one.

Both attr_name and attr_value must be a null-terminated UTF-8 encoded strings. Their contents are being copied, therefore it’s up to a function caller to properly release them.
