/* _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.
|
|
|
|
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")
|
|
rpl_environ (void) { return &environ; }
|

# undef environ

# define environ (*rpl_environ ())

Currently only MinGW is supported. See the gnulib manual regarding
|
|
Windows sockets. MinGW has the header files winsock2.h and
|
|
ws2tcpip.h that declare the sys/socket.h definitions we need. Note
|
|
that you can influence which definitions you get by setting the
|
|
WINVER symbol before including these two files. For example,
|
|
getaddrinfo is only available if _WIN32_WINNT >= 0x0501 (that
|
|
symbol is set indirectly through WINVER). You can set this by
|
|
adding AC_DEFINE(WINVER, 0x0501) to configure.ac. Note that your
|
|
code may not run on older Windows releases then. My Windows 2000
|
|
box was not able to run the code, for example. The situation is
|
|
slightly confusing because
|
|
<https://docs.microsoft.com/en-us/windows/desktop/api/ws2tcpip/nf-ws2tcpip-getaddrinfo>
|
|
suggests that getaddrinfo should be available on all Windows

releases. */
