(libgcc) what does _Unwind_Resume do ?


Hi,

I have noticed that glibc has extensive use of the _Unwind_Resume procedure
(from libgcc_eh.a) but I have failed to understand it (no luck with
the onlinedocs:
http://gcc.gnu.org/onlinedocs/gccint/Exception-handling-routines.html#Exception-handling-routines).

Can anyone please explain me what is it ? why is it needed for C programs
(I understand it is related to exception handling ?) ?

Thank you,
Sunzir.
