If the compiler does not support this 442 feature, the macro expands to an unused extern declaration. 443 444 _GL_WARN_ON_USE_ATTRIBUTE ("literal string") expands to the 445 attribute used in _GL_WARN_ON_USE. If the compiler does not support 446 this feature, it expands to empty. 447 448 These macros are useful for marking a function as a potential 449 portability trap, with the intent that "literal string" include 450 instructions on the replacement function that should be used 451 instead. 452 _GL_WARN_ON_USE is for functions with 'extern' linkage. 453 _GL_WARN_ON_USE_ATTRIBUTE is for functions with 'static' or 'inline' 454 linkage. 455 456 However, one of the reasons that a function is a portability trap is 457 if it has the wrong signature. Declaring FUNCTION with a different 458 signature in C is a compilation error, so this macro must use the 459 same type as any existing declaration so that programs that avoid 460 the problematic FUNCTION do not fail to compile merely because they 461 included a header that poisoned the function. But this implies that 462 _GL_WARN_ON_USE is only safe to use if FUNCTION is known to already 463 have a declaration. Use of this macro implies that there must not 464 be any other macro hiding the declaration of FUNCTION; but 465 undefining FUNCTION first is part of the poisoning process anyway 466 (although for symbols that are provided only via a macro, the result 467 is a compilation error rather than a warning containing 468 "literal string"). Also note that in C++, it is only safe to use if 469 FUNCTION has no overloads. 470 471 For an example, it is possible to poison 'getline' by: 472 - adding a call to gl_WARN_ON_USE_PREPARE([[#include <stdio.h>]], 473 [getline]) in configure.ac, which potentially defines 474 HAVE_RAW_DECL_GETLINE 475 - adding this code to a header that wraps the system <stdio.h>: 476 #undef getline 477 #if HAVE_RAW_DECL_GETLINE 478 _GL_WARN_ON_USE (getline, "getline is required by POSIX 2008, but" 479 "not universally present; use the gnulib module getline"); 480 #endif 481 482 It is not possible to directly poison global variables. But it is 483 possible to write a wrapper accessor function, and poison that 484 (less common usage, like &environ, will cause a compilation error 485 rather than issue the nice warning, but the end result of informing 486 the developer about their portability problem is still achieved): 487 #if HAVE_RAW_DECL_ENVIRON 488 static char *** 489 rpl_environ (void) { return &environ; } 490 _GL_WARN_ON_USE (rpl_environ, "environ is not always properly declared"); 491 # undef environ 492 # define environ (*rpl_environ ()) 493 #endif 494 or better (avoiding contradictory use of 'static' and 'extern'): 495 #if HAVE_RAW_DECL_ENVIRON 496 static char *** 497 _GL_WARN_ON_USE_ATTRIBUTE ("environ is not always properly declared") 498 rpl_environ (void) { return &environ; } 499 # undef environ 500 # define environ (*rpl_environ ()) 501 #endif 502 */ 503 #ifndef _GL_WARN_ON_USE 504 505 # if 4 < __GNUC__ || (__GNUC__ == 4 && 3 <= __GNUC_MINOR__) 506 /* A compiler attribute is available in gcc versions 4.3.0 and later. */ 507 # define _GL_WARN_ON_USE(function, message) \ 508 _GL_WARN_EXTERN_C __typeof__ (function) function __attribute__ ((__warning__ (message))) 509 # define _GL_WARN_ON_USE_ATTRIBUTE(message) \ 510 __attribute__ ((__warning__ (message))) 511 # elif __clang_major__ >= 4 512 /* Another compiler attribute is available in clang. */ 513 # define _GL_WARN_ON_USE(function, message) \ 514 _GL_WARN_EXTERN_C __typeof__ (function) function \ 515 __attribute__ ((__diagnose_if__ (1, message, "warning"))) 516 # define _GL_WARN_ON_USE_ATTRIBUTE(message) \ 517 __attribute__ ((__diagnose_if__ (1, message, "warning"))) 518 # elif __GNUC__ >= 3 && GNULIB_STRICT_CHECKING 519 /* Verify the existence of the function. */ 520 # define _GL_WARN_ON_USE(function, message) \ 521 _GL_WARN_EXTERN_C __typeof__ (function) function 522 # define _GL_WARN_ON_USE_ATTRIBUTE(message) 523 # else /* Unsupported. */ 524 # define _GL_WARN_ON_USE(function, message) \ 525 _GL_WARN_EXTERN_C int _gl_warn_on_use 526 # define _GL_WARN_ON_USE_ATTRIBUTE(message) 527 # endif 528 #endif 529 530 /* _GL_WARN_ON_USE_CXX (function, rettype_gcc, rettype_clang, parameters_and_attributes, "message") 531 is like _GL_WARN_ON_USE (function, "message"), except that in C++ mode the 532 function is declared with the given prototype, consisting of return type, 533 parameters, and attributes. 534 This variant is useful for overloaded functions in C++. _GL_WARN_ON_USE does 535 not work in this case. */ 536 #ifndef _GL_WARN_ON_USE_CXX 537 # if !defined __cplusplus 538 # define _GL_WARN_ON_USE_CXX(function,rettype_gcc,rettype_clang,parameters_and_attributes,msg) \ 539 _GL_WARN_ON_USE (function, msg) 540 # else 541 # if 4 < __GNUC__ || (__GNUC__ == 4 && 3 <= __GNUC_MINOR__) 542 /* A compiler attribute is available in gcc versions 4.3.0 and later. */ 543 # define _GL_WARN_ON_USE_CXX(function,rettype_gcc,rettype_clang,parameters_and_attributes,msg) \ 544 extern rettype_gcc function parameters_and_attributes \ 545 __attribute__ ((__warning__ (msg))) 546 # elif __clang_major__ >= 4 547 /* Another compiler attribute is available in clang. */ 548 # define _GL_WARN_ON_USE_CXX(function,rettype_gcc,rettype_clang,parameters_and_attributes,msg) \ 549 extern rettype_clang function parameters_and_attributes \ 550 __attribute__ ((__diagnose_if__ (1, msg, "warning"))) 551 # elif __GNUC__ >= 3 && GNULIB_STRICT_CHECKING 552 /* Verify the existence of the function. */ 553 # define _GL_WARN_ON_USE_CXX(function,rettype_gcc,rettype_clang,parameters_and_attributes,msg) \ 554 extern rettype_gcc function parameters_and_attributes 555 # else /* Unsupported. */ 556 # define _GL_WARN_ON_USE_CXX(function,rettype_gcc,rettype_clang,parameters_and_attributes,msg) \ 557 _GL_WARN_EXTERN_C int _gl_warn_on_use 558 # endif 559 # endif 560 #endif 561 562 /* _GL_WARN_EXTERN_C declaration; 563 performs the declaration with C linkage. */ 564 #ifndef _GL_WARN_EXTERN_C 565 # if defined __cplusplus 566 # define _GL_WARN_EXTERN_C extern "C" 567 # else 568 # define _GL_WARN_EXTERN_C extern 569 # endif 570 #endif 571 572 /* The LC_MESSAGES locale category is specified in POSIX, but not in ISO C. 573 On systems that don't define it, use the same value as GNU libintl. */ 574 #if !defined LC_MESSAGES 575 # define LC_MESSAGES 1729 576 #endif 577 578 /* On native Windows with MSVC, 'struct lconv' lacks the members int_p_* and 579 int_n_*.
