If the compiler does not support this 422 feature, the macro expands to an unused extern declaration. 423 424 _GL_WARN_ON_USE_ATTRIBUTE ("literal string") expands to the 425 attribute used in _GL_WARN_ON_USE. If the compiler does not support 426 this feature, it expands to empty. 427 428 These macros are useful for marking a function as a potential 429 portability trap, with the intent that "literal string" include 430 instructions on the replacement function that should be used 431 instead. 432 _GL_WARN_ON_USE is for functions with 'extern' linkage. 433 _GL_WARN_ON_USE_ATTRIBUTE is for functions with 'static' or 'inline' 434 linkage. 435 436 However, one of the reasons that a function is a portability trap is 437 if it has the wrong signature. Declaring FUNCTION with a different 438 signature in C is a compilation error, so this macro must use the 439 same type as any existing declaration so that programs that avoid 440 the problematic FUNCTION do not fail to compile merely because they 441 included a header that poisoned the function. But this implies that 442 _GL_WARN_ON_USE is only safe to use if FUNCTION is known to already 443 have a declaration. Use of this macro implies that there must not 444 be any other macro hiding the declaration of FUNCTION; but 445 undefining FUNCTION first is part of the poisoning process anyway 446 (although for symbols that are provided only via a macro, the result 447 is a compilation error rather than a warning containing 448 "literal string"). Also note that in C++, it is only safe to use if 449 FUNCTION has no overloads. 450 451 For an example, it is possible to poison 'getline' by: 452 - adding a call to gl_WARN_ON_USE_PREPARE([[#include <stdio.h>]], 453 [getline]) in configure.ac, which potentially defines 454 HAVE_RAW_DECL_GETLINE 455 - adding this code to a header that wraps the system <stdio.h>: 456 #undef getline 457 #if HAVE_RAW_DECL_GETLINE 458 _GL_WARN_ON_USE (getline, "getline is required by POSIX 2008, but" 459 "not universally present; use the gnulib module getline"); 460 #endif 461 462 It is not possible to directly poison global variables. But it is 463 possible to write a wrapper accessor function, and poison that 464 (less common usage, like &environ, will cause a compilation error 465 rather than issue the nice warning, but the end result of informing 466 the developer about their portability problem is still achieved): 467 #if HAVE_RAW_DECL_ENVIRON 468 static char *** 469 rpl_environ (void) { return &environ;
