5.1.2 Setting catchpoints
You can use catchpoints to cause the debugger to stop for certain kinds of program
events, such as C++ exceptions or the loading of a shared library. Use the catch command
to set a catchpoint.
catch event
Stop when event occurs. event can be any of the following:
throw The throwing of a C++ exception.
catch The catching of a C++ exception.
exec A call to exec. This is currently only available for HP-UX.
fork A call to fork. This is currently only available for HP-UX.
vfork A call to vfork. This is currently only available for HP-UX.
load
load libname
The dynamic loading of any shared library, or the loading of the
library libname. This is currently only available for HP-UX.
unload
unload libname
The unloading of any dynamically loaded shared library, or the
unloading of the library libname. This is currently only available
for HP-UX.
tcatch event
Set a catchpoint that is enabled only for one stop. The catchpoint is automat-
ically deleted after the first time the event is caught.
Use the info break command to list the current catchp oints.
There are currently som e limitations to C++ exception handling (catch throw and catch
catch) in GDB:
