line is fgets'd, and running in a while loop with counter n, d is a struct with 2 char arrays, p and q. Basically, in a few words, I want to read a line, separate it into 2 strings, one up until the first space, and the rest of the line. I clean up afterwards (\n from the file becomes \'0'). The code works, but is there a more idiomatic way to do this? What errors am I running into "unknowingly"?

    int spc = strcspn(line," ");
    strncpy(d[n].p, line, spc);
    d[n].p[spc+1]='\0';
    int l = strlen(line)-spc;
    strncpy(d[n].q, line+spc+1, l);
    char* nl = strchr(d[n].q, '\n');
    if(nl){
      *nl='\0';
    }
    n++;

Thanks.
