437/* _GL_WARN_ON_USE (function, "literal string") issues a declaration
438 for FUNCTION which will then trigger a compiler warning containing
439 the text of "literal string" anywhere that function is called, if
440 supported by the compiler. If the compiler does not support this
441 feature, the macro expands to an unused extern declaration.
442
443 _GL_WARN_ON_USE_ATTRIBUTE ("literal string") expands to the
444 attribute used in _GL_WARN_ON_USE. If the compiler does not support
445 this feature, it expands to empty.
446
447 These macros are useful for marking a function as a potential
448 portability trap, with the intent that "literal string" include
449 instructions on the replacement function that should be used
450 instead.
451 _GL_WARN_ON_USE is for functions with 'extern' linkage.
452 _GL_WARN_ON_USE_ATTRIBUTE is for functions with 'static' or 'inline'
453 linkage.
454
455 However, one of the reasons that a function is a portability trap is
456 if it has the wrong signature. Declaring FUNCTION with a different
457 signature in C is a compilation error, so this macro must use the
458 same type as any existing declaration so that programs that avoid
459 the problematic FUNCTION do not fail to compile merely because they
460 included a header that poisoned the function. But this implies that
461 _GL_WARN_ON_USE is only safe to use if FUNCTION is known to already
462 have a declaration. Use of this macro implies that there must not
463 be any other macro hiding the declaration of FUNCTION; but
464 undefining FUNCTION first is part of the poisoning process anyway
465 (although for symbols that are provided only via a macro, the result
466 is a compilation error rather than a warning containing
467 "literal string"). Also note that in C++, it is only safe to use if
468 FUNCTION has no overloads.
469
470 For an example, it is possible to poison 'getline' by:
471 - adding a call to gl_WARN_ON_USE_PREPARE([[#include <stdio.h>]],
472 [getline]) in configure.ac, which potentially defines
473 HAVE_RAW_DECL_GETLINE
474 - adding this code to a header that wraps the system <stdio.h>:
475 #undef getline
476 #if HAVE_RAW_DECL_GETLINE
477 _GL_WARN_ON_USE (getline, "getline is required by POSIX 2008, but"
478 "not universally present; use the gnulib module getline");
479 #endif
480
481 It is not possible to directly poison global variables. But it is
482 possible to write a wrapper accessor function, and poison that
483 (less common usage, like &environ, will cause a compilation error
484 rather than issue the nice warning, but the end result of informing
485 the developer about their portability problem is still achieved):
486 #if HAVE_RAW_DECL_ENVIRON
487 static char ***
488 rpl_environ (void) { return &environ; }
489 _GL_WARN_ON_USE (rpl_environ, "environ is not always properly declared");
490 # undef environ
491 # define environ (*rpl_environ ())
492 #endif
493 or better (avoiding contradictory use of 'static' and 'extern'):
494 #if HAVE_RAW_DECL_ENVIRON
495 static char ***
496 _GL_WARN_ON_USE_ATTRIBUTE ("environ is not always properly declared")
497 rpl_environ (void) { return &environ; }

573/* Converts an internet address from internal format to a printable,
574 presentable format.
575 AF is an internet address family, such as AF_INET or AF_INET6.
576 SRC points to a 'struct in_addr' (for AF_INET) or 'struct in6_addr'
577 (for AF_INET6).
578 DST points to a buffer having room for CNT bytes.
579 The printable representation of the address (in numeric form, not
580 surrounded by [...], no reverse DNS is done) is placed in DST, and
581 DST is returned. If an error occurs, the return value is NULL and
582 errno is set. If CNT bytes are not sufficient to hold the result,
583 the return value is NULL and errno is set to ENOSPC. A good value
584 for CNT is 46.
