/* See function `init_path' in `kpathsea/tex-file.c' for an example of use.
The idea is to say PVAR1C(type1, parameter1, ap) in the function header,
and then end the function with two }}'s. We do this to avoid having to
specify the argument list (with types) twice -- once in the function
header, and once in a (hypothetical) VA_START1. */
