In practice, this should only matter when there are multiple
header files with the same name. That is something we try
to avoid already, by giving headers a distinct name.
When building NetworkManager itself, we clearly want to use
double-quotes for including our own headers.
But we also want to do that in our public headers. For example:
./a.c
#include <stdio.h>
#include <nm-1.h>
void main() {
printf ("INCLUDED %s/nm-2.h\n", SYMB);
}
./1/nm-1.h
#include <nm-2.h>
./1/nm-2.h
#define SYMB "1"
./2/nm-2.h
#define SYMB "2"
$ cc -I./2 -I./1 ./a.c
$ ./a.out
INCLUDED 2/nm-2.h
Exceptions to this are
- headers in "shared/nm-utils" that include <NetworkManager.h>. These
headers are copied into projects and hence used like headers owned by
those projects.
- examples/C
Add versioned NM_DEPRECATED_IN_* and NM_AVAILABLE_IN_* macros, and tag
new/deprecated functions accordingly. (All currently-deprecated
functions are assumed to have been deprecated in 0.9.10.)
Add NM_VERSION_MIN_REQUIRED and NM_VERSION_MAX_ALLOWED macros which
can be set to determine which versions will cause warnings.
With the current settings, external consumers of the
libnm-util/libnm-glib APIs will have MIN_REQUIRED and MAX_ALLOWED both
set to NM_VERSION_0_9_8 by default, meaning they will get warnings
about functions added in 0.9.10. NM internally sets
NM_VERSION_MAX_ALLOWED to NM_VERSION_NEXT_STABLE to ensure that it is
always allowed to use all APIs.
