Federico,
The new 0.9.0 release includes file ddcutil_macros.h, which contains macro definitions DDCUTIL_VMAJOR, DDCUTIL_VMINOR, and DDCUTIL_VMICRO specifying the version number.
Note that the C API has been thoroughly reworked, and hopefully regularized. See C API Changes for Release 0.9.0.

There's no special macro, but what would it do that the API calls do not?

Hi,
is there a macro to check ddcutil major.minor.patch version?
I see there are 2 runtime functions, but i cannot see any macro for it.
Thanks!

Dealing with (possible) API breaks?
Eg, i now use it this way:
#if DDCUTIL_VERSION_MAJ == 0 && DDCUTIL_VERSION_MIN == 8 && DDCUTIL_VERSION_PATCH < 7
#define ddca_free_any_vcp_value(x) (void)x
#endif
For now, i'm creating these macros from pkg-config output:
DDCUTIL_VERSION_MAJ=$(shell pkg-config --modversion ddcutil | cut -d '.' -f1) DDCUTIL_VERSION_MIN=$(shell pkg-config --modversion ddcutil | cut -d '.' -f2) DDCUTIL_VERSION_PATCH=$(shell pkg-config --modversion ddcutil | cut -d '.' -f3)
But it would surely be better to use a macro shipped by you (as i always fear that pkg-config file is not synced).

Federico,
First, my apologies for taking to so long to reply. I've been
traveling, and the answer required a bit of thought.
The only viable way to create macros that work at build time is to
generate them from the Autotools configuration, based on the version
values in configure.ac. This in turn leads to some ugly dependency
issues.
I'd suggest creating wrapper functions, or macro equivalents, e.g.
void my_ddca_free_any_vcp_value(DDCA_Any_Vcp_Value * valrec) {
DDCA_Ddcutil_Version_Spec vspec = ddca_ddcutil_version();
if (vspec.major == 0 && vspec.minor == 8 && vspec.micro < 7)
ddca_free_any_vcp_value(valrec);
}
This makes the function call slightly more expensive, but the overhead
entails no IO so is trivial. ddcutil spends 90% of its elapsed time in
sleeps mandated by the DDC/CI protocol. Even if ddcutil's non-IO time
were reduced to 0, there would be no perceptible decrease in elapsed time.
As a heads up, the next point release will have extensive changes to the
API, base on my experience building a GUI UI.

That would give "undefined reference" on a 0.8.6 version of ddcutil, as that version would not provide ddca_free_any_vcp_value() that is still referenced in code, even if not used.
Did i misunderstand anything?
By the way is there an ETA for 0.8.7?
Thanks!

You're absolutely right. I'll give the problem some more thought.
0.8.7 is several weeks away. The bug fixes and enhancements that have
accumulated for the command line version are minor, and I expect more
API changes.
