408 | /* _GL_WARN_ON_USE (function, "literal string") issues a declaration |
409 | for FUNCTION which will then trigger a compiler warning containing |
410 | the text of "literal string" anywhere that function is called, if |
411 | supported by the compiler. If the compiler does not support this |
412 | feature, the macro expands to an unused extern declaration. |
413 | |
414 | _GL_WARN_ON_USE_ATTRIBUTE ("literal string") expands to the |
415 | attribute used in _GL_WARN_ON_USE. If the compiler does not support |
416 | this feature, it expands to empty. |
417 | |
418 | These macros are useful for marking a function as a potential |
419 | portability trap, with the intent that "literal string" include |
420 | instructions on the replacement function that should be used |
421 | instead. |
422 | _GL_WARN_ON_USE is for functions with 'extern' linkage. |
423 | _GL_WARN_ON_USE_ATTRIBUTE is for functions with 'static' or 'inline' |
424 | linkage. |
425 | |
426 | However, one of the reasons that a function is a portability trap is |
427 | if it has the wrong signature. Declaring FUNCTION with a different |
428 | signature in C is a compilation error, so this macro must use the |
429 | same type as any existing declaration so that programs that avoid |
430 | the problematic FUNCTION do not fail to compile merely because they |
431 | included a header that poisoned the function. But this implies that |
432 | _GL_WARN_ON_USE is only safe to use if FUNCTION is known to already |
433 | have a declaration. Use of this macro implies that there must not |
434 | be any other macro hiding the declaration of FUNCTION; but |
435 | undefining FUNCTION first is part of the poisoning process anyway |
436 | (although for symbols that are provided only via a macro, the result |
437 | is a compilation error rather than a warning containing |
438 | "literal string"). Also note that in C++, it is only safe to use if |
439 | FUNCTION has no overloads. |
440 | |
441 | For an example, it is possible to poison 'getline' by: |
442 | - adding a call to gl_WARN_ON_USE_PREPARE([[#include <stdio.h>]], |
443 | [getline]) in configure.ac, which potentially defines |
444 | HAVE_RAW_DECL_GETLINE |
445 | - adding this code to a header that wraps the system <stdio.h>: |
446 | #undef getline |
447 | #if HAVE_RAW_DECL_GETLINE |
448 | _GL_WARN_ON_USE (getline, "getline is required by POSIX 2008, but" |
449 | "not universally present; use the gnulib module getline"); |
450 | #endif |
451 | |
452 | It is not possible to directly poison global variables. But it is |
453 | possible to write a wrapper accessor function, and poison that |
454 | (less common usage, like &environ, will cause a compilation error |
455 | rather than issue the nice warning, but the end result of informing |
456 | the developer about their portability problem is still achieved): |
457 | #if HAVE_RAW_DECL_ENVIRON |
458 | static char *** |
459 | rpl_environ (void) { return &environ; } |
460 | _GL_WARN_ON_USE (rpl_environ, "environ is not always properly declared"); |
461 | # undef environ |
462 | # define environ (*rpl_environ ()) |
463 | #endif |
464 | or better (avoiding contradictory use of 'static' and 'extern'): |
