Hi all,
I am calling a program written in C inside Python using ctypes,
and it seems that sometimes the program in C crashes while it's being
used in Python.
Even under the circumstances, I want to get the Python program going
by handling the segmentation fault.
I've already searched the Internet, but couldn't get the right answer
to catch them.
Could any of you please let me know how to deal with this and catch
the segmentation fault in Python?
Thanks,
Justin.
Segmentation fault isn't exactly an exception that you can catch. It
usually means something has gone horribly wrong, like dereferencing
invalid pointer, trying to access memory out of process's range. Since
if you run out of memory Python simply raises MemoryError exception,
which you can catch. So that is not the case for segmentation fault.
Either fix the program so it doesn't crash,or run the offending
module and the C code in a subprocess.
