[libdvdnav-devel] Can We Assume C99 Yet?

[Lawrence D'Oliveiro]

I see you are assuming that <stdint.h> is present, which is only a
requirement in C99 and later versions of the C standard. What about
making use of <stdbool.h> as well?

For example, in src/dvd_reader.c, there is the “have_css” flag. This
could be usefully defined as a bool rather than an int. I do note that
the routine “dvdinput_setup” in src/dvd_input.c returns an int rather
than a bool, and that it is an exported symbol in the .so file, even
though it is not declared in any of the public include files. Could
this be changed to a bool as well? Or is it considered part of the
public API?
