Simple script to plot sphere in 3d via parametric equations, wait until we close the gnuplot window, or hit button. Execute it with ./splot-sphere.sh. You might have to `chmod 755 splot-sphere.sh` first.

Demonstrate that we actually don't need header file especially for functions that used internally, just compile them together (technically link obj files together).

You can compile with (technically both are the same)

  1. Compile both source files at the same time
  • gcc test-objfile.c test-objfile-companion.c
  1. Compile each one individually, then output objf file to link together
  • gcc -c test-objfile.c -o test-objfile.o
  • gcc -c test-objfile-companion.c -o test-objfile-companion.o

Test code reading file from user's home directory. As per POSIX, it requires OS to set HOME environment variable, so it should always be there. Updated: see the full repo at https://github.com/abzico/libpng_example
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
int main(int argc, char** argv)
{
// get home directory (it's always set as HOME required by POSIX)
const char* homedir = getenv("HOME");
char tempfile[128];
