15 * env_attr_walk takes as input an "attr_list" that takes the form:
16 * attributes = [^,:\s]*
17 * entry = name[:attributes]
19 * It will call the "callback" function with the "name" and "attributes"
20 * The callback may return a non-0 to abort the list walk.
21 * This return value will be passed through to the caller.
22 * 0 is returned on success.

29 * env_attr_lookup takes as input an "attr_list" with the same form as above.
30 * It also takes as input a "name" to look for.
31 * If the name is found in the list, it's value is copied into "attributes".
32 * There is no protection on attributes being too small for the value.
33 * It returns -1 if attributes is NULL, 1 if "name" is not found, 2 if
34 * "attr_list" is NULL.
35 * Returns 0 on success.
