/* _GL_WARN_ON_USE (function, "literal string") issues a declaration
|
||||
for FUNCTION which will then trigger a compiler warning containing
|
||||
the text of "literal string" anywhere that function is called, if
|
||||
supported by the compiler. If the compiler does not support this
|
||||
feature, the macro expands to an unused extern declaration.
|
||||
|
||||
This macro is useful for marking a function as a potential
|
||||
portability trap, with the intent that "literal string" include
|
||||
instructions on the replacement function that should be used
|
||||
instead. However, one of the reasons that a function is a
|
||||
portability trap is if it has the wrong signature. Declaring
|
||||
FUNCTION with a different signature in C is a compilation error, so
|
||||
this macro must use the same type as any existing declaration so
|
||||
that programs that avoid the problematic FUNCTION do not fail to
|
||||
compile merely because they included a header that poisoned the
|
||||
function. But this implies that _GL_WARN_ON_USE is only safe to
|
||||
use if FUNCTION is known to already have a declaration. Use of
|
||||
this macro implies that there must not be any other macro hiding
|
||||
the declaration of FUNCTION; but undefining FUNCTION first is part
|
||||
of the poisoning process anyway (although for symbols that are
|
||||
provided only via a macro, the result is a compilation error rather
|
||||
than a warning containing "literal string"). Also note that in
|
||||
C++, it is only safe to use if FUNCTION has no overloads.
|
||||
|
||||
For an example, it is possible to poison 'getline' by:
|
||||
- adding a call to gl_WARN_ON_USE_PREPARE([[#include <stdio.h>]],
|
||||
[getline]) in configure.ac, which potentially defines
|
||||
HAVE_RAW_DECL_GETLINE
|
||||
- adding this code to a header that wraps the system <stdio.h>:
|
||||
#undef getline
|
||||
#if HAVE_RAW_DECL_GETLINE
|
||||
_GL_WARN_ON_USE (getline, "getline is required by POSIX 2008, but"
|
||||
"not universally present; use the gnulib module getline");
|
||||
#endif
|
||||
|
||||
It is not possible to directly poison global variables. But it is
|
||||
possible to write a wrapper accessor function, and poison that
|
||||
(less common usage, like &environ, will cause a compilation error
|
||||
rather than issue the nice warning, but the end result of informing
|
||||
the developer about their portability problem is still achieved):
|
||||
#if HAVE_RAW_DECL_ENVIRON
|
||||
static char ***rpl_environ (void) { return &environ; }
|
||||
_GL_WARN_ON_USE (rpl_environ, "environ is not always properly declared");
