/* _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.
|
||||
|
||||
_GL_WARN_ON_USE_ATTRIBUTE ("literal string") expands to the
|
||||
attribute used in _GL_WARN_ON_USE. If the compiler does not support
|
||||
this feature, it expands to empty.
|
||||
|
||||
These macros are 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.
|
||||
_GL_WARN_ON_USE is for functions with 'extern' linkage.
|
||||
_GL_WARN_ON_USE_ATTRIBUTE is for functions with 'static' or 'inline'
|
||||
linkage.
|
||||
|
||||
_GL_WARN_ON_USE should not be used more than once for a given function
|
||||
in a given compilation unit (because this may generate a warning even
|
||||
if the function is never called).
|
||||
|
||||
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");
|
||||
# undef environ
|
||||
# define environ (*rpl_environ ())
|
||||
#endif
|
||||
or better (avoiding contradictory use of 'static' and 'extern'):
|
||||
#if HAVE_RAW_DECL_ENVIRON
|
||||
static char ***
|
||||
_GL_WARN_ON_USE_ATTRIBUTE ("environ is not always properly declared")
|
||||
