/* _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

/* Converts an internet address from internal format to a printable,

AF is an internet address family, such as AF_INET or AF_INET6.

SRC points to a 'struct in_addr' (for AF_INET) or 'struct in6_addr'
|

(for AF_INET6).

DST points to a buffer having room for CNT bytes.
|

The printable representation of the address (in numeric form, not

DST is returned. If an error occurs, the return value is NULL and

the return value is NULL and errno is set to ENOSPC. A good value
