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 ]], - [getline]) in configure.ac, which potentially defines - HAVE_RAW_DECL_GETLINE - - adding this code to a header that wraps the system : - #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 - # define environ (*rpl_environ ()) - #endif - */ -#ifndef _GL_WARN_ON_USE - -# if 4 < __GNUC__ || (__GNUC__ == 4 && 3 <= __GNUC_MINOR__) -/* A compiler attribute is available in gcc versions 4.3.0 and later. */ -# define _GL_WARN_ON_USE(function, message) \ -_GL_WARN_EXTERN_C __typeof__ (function) function __attribute__ ((__warning__ (message))) -# define _GL_WARN_ON_USE_ATTRIBUTE(message) \ - __attribute__ ((__warning__ (message))) -# elif __clang_major__ >= 4 -/* Another compiler attribute is available in clang. */ -# define _GL_WARN_ON_USE(function, message) \ -_GL_WARN_EXTERN_C __typeof__ (function) function \ - __attribute__ ((__diagnose_if__ (1, message, "warning"))) -# define _GL_WARN_ON_USE_ATTRIBUTE(message) \ - __attribute__ ((__diagnose_if__ (1, message, "warning"))) -# elif __GNUC__ >= 3 && GNULIB_STRICT_CHECKING -/* Verify the existence of the function. */ -# define _GL_WARN_ON_USE(function, message) \ -_GL_WARN_EXTERN_C __typeof__ (function) function -# define _GL_WARN_ON_USE_ATTRIBUTE(message) -# else /* Unsupported. */ -# define _GL_WARN_ON_USE(function, message) \ -_GL_WARN_EXTERN_C int _gl_warn_on_use -# define _GL_WARN_ON_USE_ATTRIBUTE(message) -# endif -#endif - -/* _GL_WARN_ON_USE_CXX (function, rettype_gcc, rettype_clang, parameters_and_attributes, "message") - is like _GL_WARN_ON_USE (function, "message"), except that in C++ mode the - function is declared with the given prototype, consisting of return type, - parameters, and attributes. - This variant is useful for overloaded functions in C++. _GL_WARN_ON_USE does - not work in this case. */ -#ifndef _GL_WARN_ON_USE_CXX -# if !defined __cplusplus -# define _GL_WARN_ON_USE_CXX(function,rettype_gcc,rettype_clang,parameters_and_attributes,msg) \ - _GL_WARN_ON_USE (function, msg) -# else -# if 4 < __GNUC__ || (__GNUC__ == 4 && 3 <= __GNUC_MINOR__) -/* A compiler attribute is available in gcc versions 4.3.0 and later. */ -# define _GL_WARN_ON_USE_CXX(function,rettype_gcc,rettype_clang,parameters_and_attributes,msg) \ -extern rettype_gcc function parameters_and_attributes \ - __attribute__ ((__warning__ (msg))) -# elif __clang_major__ >= 4 -/* Another compiler attribute is available in clang. */ -# define _GL_WARN_ON_USE_CXX(function,rettype_gcc,rettype_clang,parameters_and_attributes,msg) \ -extern rettype_clang function parameters_and_attributes \ - __attribute__ ((__diagnose_if__ (1, msg, "warning"))) -# elif __GNUC__ >= 3 && GNULIB_STRICT_CHECKING -/* Verify the existence of the function. */ -# define _GL_WARN_ON_USE_CXX(function,rettype_gcc,rettype_clang,parameters_and_attributes,msg) \ -extern rettype_gcc function parameters_and_attributes -# else /* Unsupported. */ -# define _GL_WARN_ON_USE_CXX(function,rettype_gcc,rettype_clang,parameters_and_attributes,msg) \ -_GL_WARN_EXTERN_C int _gl_warn_on_use -# endif -# endif -#endif - -/* _GL_WARN_EXTERN_C declaration; - performs the declaration with C linkage. */ -#ifndef _GL_WARN_EXTERN_C -# if defined __cplusplus -# define _GL_WARN_EXTERN_C extern "C" -# else -# define _GL_WARN_EXTERN_C extern -# endif -#endif - -#ifdef __cplusplus -/* Helper macros to define type-generic function FUNC as overloaded functions, - rather than as macros like in C.
