I believe the pth_key_***() APIs are used for "thread local storage". So does it really matter whats the data value for this key in other threads ?. Please correct me If I am wrong. I think it would be great if the documentation for Pth <http://www.gnu.org/software/pth/pth-manual.html> could explain something about what all the application should do before destroying a private key. > Additionally to clearing the data, the corresponding destructor >has to be called first, too. I think pth_key_delete() is used to destroy only a *single key* and not to free the complete memory allocated for storing the private data values for a thread. So is it required to call the destructor function from a pth_key_delete () ? >The question just is: should pth_key_delete() return with e.g. EBUSY >in case any thread still uses data associated with the key or should >it instead automatically free all the data associated with it in all >threads. I personally think pth_key_delete() should return EBUSY. >Any objections? I think the pth_key_delete() should be a little more intelligent rather than asking the application to handle such conditions. Or does current implementation of these APIs restricts *a thread* from freeing only a specific key. If that is the case then I think the pth_key_delete() should return EBUSY. PS: I am not able see the mails posted after "10/08/2004" in the Pth mailing list archives. <http://www.mail-archive.com/[EMAIL PROTECTED]/maillist.html>. Does anyone else in this group is facing this problem ?
