| /* _GL_WARN_ON_USE (function, "literal string") issues a declaration |
| for FUNCTION which will then trigger a compiler warning containing |
| the text of "literal string" anywhere that function is called, if |
| supported by the compiler. 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. 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; } |
