* \a[c/posix/inet/pton.c]: `inet_pton` demo. Adapted from `man inet_pton` on <Ubuntu 23.04>. Usage:
  ``
  ./pton.out 192.187.1.42
  ``
  Output:
  ``
  0xc0bb012a
  ``
  So we see that the strings was converted to an integer, e.g.:
  * 0xc0 = 192
  * 0xbb = 187
  * 0x01 = 1
  * 0x2a = 42

  ``
  Output:
  ``
