UNIX & GNU/Linux - System calls - Using getenv()

The getenv() function is a Linux system call function.

It is designed to know what is the name of an environment variable.

The main use is for the "TERM" variable. Let's see an example of the getenv() function:

int     main()
  const char *name;

  name = "TERM";
  printf("My terminal is %s.\n", getenv(name));
  return (0);
