caddr_t is legacy BSD and should be avoided.

[PATCH 3/3] unit: prevent use of glibc's error(3)

[Natanael Copa]

When building the test-sdp we don't want src/sdpd-request.c end up
using the incompatible GNU libc's error(3).

This also fixes building on musl libc which misses the error(3) GNU
extension.

We could perhaps do the same thing we did in test-avdtp.c, build with
log support and add the following check:

if (g_test_verbose())
__btd_log_init("*", 0);

I believe the correct approach here is to include sys/stat.h on all
files that include textfile.h. We (usually) don't #include system
headers inside internal headers.

with code in src/shared/*.h we started to include the system headers that are required from the header, but you are correct, we don’t do that for internal src/*.h headers.

Also we do not use circular inclusion protection from internal headers. So I ripped the stupid __TEXTFILE_H stuff out now.

Regards

Marcel

The header itself uses mode_t:
./src/textfile.h:27:1: error: unknown type name 'mode_t'

So all the files that include textfiles.h needs to include sys/stat.h
*before* the include textfile.h in that case.

I'd say that all filesm that uses mode_t including textfile.h should
include sys/stat.h.

I can make a new patch for either. Just let me know what you want.

This is how we have done so far for files in src/* (for src/shared/ as
Marcel mentioned this is being done differently). So I suggest you do
this way.

Note that several files (about 5 out of 10) already include
sys/stat.h, according to a quick grep I did. Maybe they are just not
in the right order.

Seems this patch was forgotten. It has now finally been applied
upstream.
