Sets strftime like header format strings, to be printed on the
left, center and right of the top of each page. The strings may
include strftime(3) codes which will be expanded at print time.
All strftime() codes are accepted, with the addition of N for the
page number and Q for the page count.
separator specifies if a solid line should be drawn to separate
the header from the document text.
If NULL is given for any of the three arguments, that particular
string will not be printed.
For the header to be printed, in
addition to specifying format strings, you need to enable header
printing with gtk_source_print_compositor_set_print_header().
This function cannot be called anymore after the first call to the
gtk_source_print_compositor_paginate() function.
Since 2.2
