mail::Header::list — Create a list of headers.
#include <libmail/headers.H>
mail::Header::list headers;
headers << mail::Header::encoded("Subject", "Hello", "iso-8859-1")
<< mail::header::addresslist("To")
("John", "john@example.com")
("Tom", "tom@example.com")
<< mail::Header::mime("Content-Type", "text/plain")
("charset", "iso-8859-1");
std::cout << (std::string)headers;
This is a helper class for formatting a list of headers.
Each header is specified, using the << operator, which can take any
combination of mail::Header::addresslist(3x),
mail::Header::encoded(3x),
mail::Header::mime(3x), or
mail::Header::plain(3x).
The << operator makes
an internal copy of the header object. The original object
may be destroyed after the operator returns.
The std::string operator
formats all headers, and returns the set of E-mail headers as
a single string. Long headers are folded accordingly.
