Process section

const int nin_ is a number of incoming particles
const int nout_ is a number of outgoing particles
const int nprc_ is a total number of subprocesses
char processch[] contains the process name. It is needed to be only displayed on the screen during the n_comphep_c session.
int pinf_(int nsub, int nprtcl, char *name, double * mass) returns the name and the mass of particle with the nprtcl ordering number for the subprocess nsub. First nin_  numbers are reserved for incoming particles, while next nout_ are assigned to outgoing ones. One can substitute the NULL constant instead of any outgoing parameter if the corresponding information is not needed. The function returns $0$ if $nsub <= nprc\_$ and $nprtcl <= nin\_+nout\_$, otherwise 1 is returned.
