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;
