I've tried pthread_self() and syscall(_NR_gettid) but they just return the identifier of the initiating thread rather than the thread I'm calling them from. This makes debugging extremely difficult, for example I can see from 'ps -AL' that some of the threads are doing the <defunct> zombie thing, but I don't know which ones they are.</FONT></SPAN></DIV> <DIV><SPAN class=681133309-13112007><FONT face=Arial size=2></FONT></SPAN> </DIV> <DIV><SPAN class=681133309-13112007><FONT face=Arial size=2>Any suggestions</FONT></SPAN></DIV> <DIV><SPAN class=681133309-13112007><FONT face=Arial size=2></FONT></SPAN> </DIV> <DIV><SPAN class=681133309-13112007><FONT face=Arial size=2>Thanks</FONT></SPAN></DIV> <DIV><SPAN class=681133309-13112007><FONT face=Arial size=2></FONT></SPAN> </DIV> <DIV><SPAN class=681133309-13112007><FONT face=Arial size=2>John</FONT></SPAN></DIV> <TABLE> <TBODY> <TR> <TD bgColor=#ffffff>********************************************************************<BR>This email and any attachments are confidential to the intended recipient and may also be privileged.
