* @map: the typed strmap to search.
* @member: the string to search for.
*
- * Returns the value, or NULL if it isn't in the map.
+ * Returns the value, or NULL if it isn't in the map (and sets errno = ENOENT).
*
* Example:
* int *val = strmap_get(&map, "hello");
* @member: the string to remove from the map.
* @valuep: the value (if non-NULL)
*
- * This returns the string which was passed to strmap_map(), or NULL.
+ * This returns the string which was passed to strmap_map(), or NULL if
+ * it was not in the map (and sets errno = ENOENT).
+ *
* This means that if you allocated a string (eg. using strdup()), you
* can free it here. Similarly, the value is returned in @valuep if
* @valuep is not NULL.
