Detailed Description

Class for inserting binary regions types into Pantheios diagnostic logging statements.

This class formats a binary region into a string, thereby enabling it to be inserted into a logging statement. Consider the following statement:

  int         ar[2] = { 0x00112233, 0x44556677 };
  char        s[]   = "abc";
  std::string str("def");

  pantheios::log(pantheios::notice, "s=", s, ", b64=", pantheios::b64(ar, sizeof(ar)), ", str=", str);

This will produce the output:

   s=abc, b64=0011223344556677, str=def

The bytes can be grouped and these groups separated. Consider the following statement:

  int         ar[2] = { 0x00112233, 0x44556677 };
  char        s[]   = "abc";
  std::string str("def");

  pantheios::log(pantheios::notice, "s=", s, ", b64=", pantheios::b64(ar, sizeof(ar), 2, "-"), ", str=", str);

This will produce the output:

   s=abc, b64=2233-0011-6677-4455, str=def

The output can be split into lines. Consider the following statement:

  int         ar[2] = { 0x00112233, 0x44556677 };
  char        s[]   = "abc";
  std::string str("def");

  pantheios::log(pantheios::notice, "s=", s, ", b64=", pantheios::b64(ar, sizeof(ar), 2, "-", 3, "\n\t"), ", str=", str);

This will produce the output:

  s=abc, b64=2233-0011-6677
          4455, str=def
