Does the strace tool working with standard Win32 tools. Because I need
a generic tool tracing file accesses on CygWin+Win32 native tools (not
only CygWin programs using cygwin.dll).
I tried or C:\cygwin\bin>strace --trace-children --mask=all --pid=5012
(5012 was the windows pid of a windows cmd.exe instance)
C:\cygwin\bin>strace --trace-children --mask=all cmd.exe
But At anytime, something was appearing in strace or in the log file (I
tried also with the --output but nothing !
I tried with ls.exe & strace works. So my (personal ;) ) conclusion, is
strace cannot track file accesses on all executables, only cygwin
executable :(

I think this is due because bash execute at sometimes others instances
of bash (looking to my truss log file)

Yes, ok, but so, how to trace cygwin+native Win32 program together ?
