Hi Guosheng,
If I understand correctly, you want to use only MTCP (single-process)
and not the more general DMTCP. If that is so, the easiest way to see
how to use it will be to do:
cd mtcp
make check
[ When the program starts, type anything followed by <return>.
As you continue to interact with the program, you will see it
checkpoint, and automatically restart. ]
You can read the 'check' target of mtcp/Makefile to see how it works.
Essentially, assuming libmtcp.so is in the current directory, it's:
# Compile
env LD_LIBRARY_PATH=. ${CC} $(MTCP_CFLAGS) -o testmtcp testmtcp.o
-Wl,--export-dynamic libmtcp.so
# Run (will checkpoint itself at intervals; Read testmtcp.c)
env LD_LIBRARY_PATH=. ./testmtcp
# Restart it this way.
./mtcp_restart testmtcp.mtcp
Best,
- Gene

Android is increasing in popularity, but the open development platform that
developers love is also attractive to malware creators. Download this white
paper to learn more about secure code signing practices that can help keep
Android apps secure.
