I think the Solaris thread-safety attributes are a bit too simplistic to capture the whole scope of thread safety issues for functions operating on mutable data. > For example, Solaris 11.2: > http://docs.oracle.com/cd/E36784_01/html/E36874/readdir-3c.html “It is safe to use readdir() in a threaded application, so long as only one thread reads from the directory stream at any given time. The readdir() function is generally preferred over the readdir_r() function.” Florian
