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 <stdio.h>]], + [getline]) in configure.ac, which potentially defines + HAVE_RAW_DECL_GETLINE + - adding this code to a header that wraps the system <stdio.h>: + #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.
