If the compiler does not support this feature, the macro expands to an unused extern declaration. This macro is 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. 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 */ #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) \ extern __typeof__ (function) function __attribute__ ((__warning__ (message))) # elif __GNUC__ >= 3 && GNULIB_STRICT_CHECKING /* Verify the existence of the function. */ # define _GL_WARN_ON_USE(function, message) \ extern __typeof__ (function) function # else /* Unsupported. */ # define _GL_WARN_ON_USE(function, message) \ _GL_WARN_EXTERN_C int _gl_warn_on_use # endif #endif /* _GL_WARN_ON_USE_CXX (function, rettype, parameters_and_attributes, "string") is like _GL_WARN_ON_USE (function, "string"), except that the function is declared with the given prototype, consisting of return type, parameters, and attributes.
