I have a question about running Lammps as a library. I try to modify the example COUPLE/simple.c and I want to transmit some parameters in lammps_open(…) command.
But I don’t know what I should put into the arg[0]. I tried to leave it NULL and got this error:
[Karen-HP:10600] *** Process received signal ***

When I tried original “simple.c” code, it compiled and ran correctly, so it’s not a compilation error.
Could you give me an advice, please?

the arg array is used like the argv vector in C, i.e. the second
argument to the main() function.
thus arg[0] would be the name of the executable. it can be any valid
string (i.e. a pointer to char).
