int b=15; int a=20;
int main() { mkdir("/sd/Sistem", 0777);
FILE *fp = fopen("/sd/Sistem/canbus.csv", "w"); if(fp == NULL) { error("Could not open file for write\n"); }
fprintf(fp, "%d%d \n",a,b); fprintf(fp, "aaaaaaaaaaaaaaaaaaa"); fclose(fp); }

You need to seperate your two values, now you print them right after each other. How to do this depends on your country/pc settings. For the US:
fprintf(fp, "%d,%d \n",a,b);
For (mainland?) Europe:
fprintf(fp, "%d;%d \n",a,b);
