Add missing argtypes declarations in lammps.py 2020-08-28 15:12:36 -04:00

Ensure LAMMPS pointer is of type c_void_p 
Fixes segfaults caused by API change. The API change in
lammps_open and lammps_open_no_mpi makes them return the LAMMPS pointer
via their return value. However due to how ctypes operates, even
if restype is specified to be c_void_p, the function returns an integer.

Without the proper type of the pointer, calling functions without arglists would default
to using 32bit integers to pass an argument, which cuts away parts of the 64bit pointer.
Subsequently, resolving the truncated pointer in the library causes segfaults.

This commit fixes the root cause. But it also highlights the need of specifying
the arglists of all library functions.

Axel Kohlmeyer 5bf8e1bc5b add ability to retrieve the number of local rows for computes returning local data 
this is done supporting the combination of type == 2 with style == 0,
i.e. a local scalar, which is not available in C++ (but there one can
access the compute style data member directly. for the python interface,
the pointer is automatically dereferenced and returned as a c_int.
