Hello deBUGies,

        Is there any way to debug what are all the "system calls" usage and process happening over on the program.

        I have written a simple program which gets the a string.I have made it to wait for the input and using that process-id,
        I have attached the process with gdb.Now the "where" command gives the stackframes about the system calls information.
        To find the processings of other system calls what is the way.  
             
Regards,
Muthu.

BTW, a wish-list item is for GDB to directly include strace support.

What would that look like?
Would you just type
(gdb) strace <args>

and have it print out what strace does now while it runs,
or do you have something more in mind?

who knows, something like:

(gdb) {set,show} strace <see help handle>

or

(gdb) catch syscall all
Catch point 5 created
(gdb) commands 5
silent
backtrace
continue
end
(gdb)

(and don't get me started about that "silent" "feature" :-)

Hai all,

Regarding to the system calls debuggin,in linux using the process id 
of the debugging file with strace we can find.

In HP-UNIX ,how we can trace the system calls with the GDB support.

Regards,
Muthu.

Please try tusc command, not sure if it is there by default.
