If the compiler does not support this 420 feature, the macro expands to an unused extern declaration. 421 422 _GL_WARN_ON_USE_ATTRIBUTE ("literal string") expands to the 423 attribute used in _GL_WARN_ON_USE. If the compiler does not support 424 this feature, it expands to empty. 425 426 These macros are useful for marking a function as a potential 427 portability trap, with the intent that "literal string" include 428 instructions on the replacement function that should be used 429 instead. 430 _GL_WARN_ON_USE is for functions with 'extern' linkage. 431 _GL_WARN_ON_USE_ATTRIBUTE is for functions with 'static' or 'inline' 432 linkage. 433 434 However, one of the reasons that a function is a portability trap is 435 if it has the wrong signature. Declaring FUNCTION with a different 436 signature in C is a compilation error, so this macro must use the 437 same type as any existing declaration so that programs that avoid 438 the problematic FUNCTION do not fail to compile merely because they 439 included a header that poisoned the function. But this implies that 440 _GL_WARN_ON_USE is only safe to use if FUNCTION is known to already 441 have a declaration. Use of this macro implies that there must not 442 be any other macro hiding the declaration of FUNCTION; but 443 undefining FUNCTION first is part of the poisoning process anyway 444 (although for symbols that are provided only via a macro, the result 445 is a compilation error rather than a warning containing 446 "literal string"). Also note that in C++, it is only safe to use if 447 FUNCTION has no overloads. 448 449 For an example, it is possible to poison 'getline' by: 450 - adding a call to gl_WARN_ON_USE_PREPARE([[#include <stdio.h>]], 451 [getline]) in configure.ac, which potentially defines 452 HAVE_RAW_DECL_GETLINE 453 - adding this code to a header that wraps the system <stdio.h>: 454 #undef getline 455 #if HAVE_RAW_DECL_GETLINE 456 _GL_WARN_ON_USE (getline, "getline is required by POSIX 2008, but" 457 "not universally present; use the gnulib module getline"); 458 #endif 459 460 It is not possible to directly poison global variables. But it is 461 possible to write a wrapper accessor function, and poison that 462 (less common usage, like &environ, will cause a compilation error 463 rather than issue the nice warning, but the end result of informing 464 the developer about their portability problem is still achieved): 465 #if HAVE_RAW_DECL_ENVIRON 466 static char *** 467 rpl_environ (void) { return &environ; } 468 _GL_WARN_ON_USE (rpl_environ, "environ is not always properly declared"); 469 # undef environ 470 # define environ (*rpl_environ ()) 471 #endif 472 or better (avoiding contradictory use of 'static' and 'extern'): 473 #if HAVE_RAW_DECL_ENVIRON 474 static char *** 475 _GL_WARN_ON_USE_ATTRIBUTE ("environ is not always properly declared") 476 rpl_environ (void) { return &environ; } 477 # undef environ 478 # define environ (*rpl_environ ()) 479 #endif 480 */ 481#ifndef _GL_WARN_ON_USE 482 483# if 4 < __GNUC__ || (__GNUC__ == 4 && 3 <= __GNUC_MINOR__) 484/* A compiler attribute is available in gcc versions 4.3.0 and later. */ 485# define _GL_WARN_ON_USE(function, message) \ 486extern __typeof__ (function) function __attribute__ ((__warning__ (message))) 487# define _GL_WARN_ON_USE_ATTRIBUTE(message) \ 488 __attribute__ ((__warning__ (message))) 489# elif __GNUC__ >= 3 && GNULIB_STRICT_CHECKING 490/* Verify the existence of the function. */ 491# define _GL_WARN_ON_USE(function, message) \ 492extern __typeof__ (function) function 493# define _GL_WARN_ON_USE_ATTRIBUTE(message) 494# else /* Unsupported. */ 495# define _GL_WARN_ON_USE(function, message) \ 496_GL_WARN_EXTERN_C int _gl_warn_on_use 497# define _GL_WARN_ON_USE_ATTRIBUTE(message) 498# endif 499#endif 500 501/* _GL_WARN_ON_USE_CXX (function, rettype, parameters_and_attributes, "string") 502 is like _GL_WARN_ON_USE (function, "string"), except that in C++ mode the 503 function is declared with the given prototype, consisting of return type, 504 parameters, and attributes. 505 This variant is useful for overloaded functions in C++. _GL_WARN_ON_USE does 506 not work in this case. */ 507#ifndef _GL_WARN_ON_USE_CXX 508# if !defined __cplusplus 509# define _GL_WARN_ON_USE_CXX(function,rettype,parameters_and_attributes,msg) \ 510 _GL_WARN_ON_USE (function, msg) 511# else 512# if 4 < __GNUC__ || (__GNUC__ == 4 && 3 <= __GNUC_MINOR__) 513# define _GL_WARN_ON_USE_CXX(function,rettype,parameters_and_attributes,msg) \ 514extern rettype function parameters_and_attributes \ 515 __attribute__ ((__warning__ (msg))) 516# elif __GNUC__ >= 3 && GNULIB_STRICT_CHECKING 517/* Verify the existence of the function. */ 518# define _GL_WARN_ON_USE_CXX(function,rettype,parameters_and_attributes,msg) \ 519extern rettype function parameters_and_attributes 520# else /* Unsupported. */ 521# define _GL_WARN_ON_USE_CXX(function,rettype,parameters_and_attributes,msg) \ 522_GL_WARN_EXTERN_C int _gl_warn_on_use 523# endif 524# endif 525#endif 526 527/* _GL_WARN_EXTERN_C declaration; 528 performs the declaration with C linkage. */ 529#ifndef _GL_WARN_EXTERN_C 530# if defined __cplusplus 531# define _GL_WARN_EXTERN_C extern "C" 532# else 533# define _GL_WARN_EXTERN_C extern 534# endif 535#endif 536 537/* Some systems don't define struct timespec (e.g., AIX 4.1). 538 Or they define it with the wrong member names or define it in <sys/time.h> 539 (e.g., FreeBSD circa 1997).
