我的MPI C程序有问题.这是代码:

void wantEat(int p, int rank, char *state, char* stateLeft, char* stateRight){

    char *s;

        MPI_Send(state, strlen(state)+1, MPI_CHAR,
                (rank - 1 + p) % p, 0, MPI_COMM_WORLD);
        MPI_Send(state, strlen(state)+1, MPI_CHAR,
                (rank + 1) % p, 0, MPI_COMM_WORLD);

        /* if …
