I'm trying to use strace to attach to a running process (strace -p pid) but I'm not getting anywhere. To be precise, I get no output until the target process exits, when I get, for example, 'Attached to pid 2236 (windows pid 2156)', and no strace output. If I strace strace doing this, I get: $ strace strace -p 2156 ********************************************** Program name: C:\cygwin\bin\strace.exe (324) App version: 1003.10, api: 0.51 DLL version: 1003.10, api: 0.51 DLL build: 2002-02-25 11:14 OS version: Windows NT-5.0 Date/Time: 2002-05-24 05:20:43 ********************************************** 542 7126 [unknown (0x90C)] strace 324 sig_send: pid 2156, signal -1, its_me 0 148 7274 [unknown (0x90C)] strace 324 getsem: pid 2156, ppid 1860, wait 1000, initializing 0 233 7507 [unknown (0x90C)] strace 324 sig_send: Not waiting for sigcomplete. its_me 0 signal -1 85 7592 [unknown (0x90C)] strace 324 sig_send: returning 0 from sending signal -1 Attached to pid 2156 (windows pid 2420) The strace output appears as soon as I run the strace command; the 'Attached ...' message appears once the target dies. Am I missing something? (presumably something obvious . . .) or are the gremlins having a party in my machine? Perplexed and seeking solace, // Conrad p.s. I've attached the usual cygcheck output to this message.
