| 422 | /* _GL_WARN_ON_USE (function, "literal string") issues a declaration |
| 423 | for FUNCTION which will then trigger a compiler warning containing |
| 424 | the text of "literal string" anywhere that function is called, if |
| 425 | supported by the compiler. If the compiler does not support this |
| 426 | feature, the macro expands to an unused extern declaration. |
| 427 | |
| 428 | _GL_WARN_ON_USE_ATTRIBUTE ("literal string") expands to the |
| 429 | attribute used in _GL_WARN_ON_USE. If the compiler does not support |
| 430 | this feature, it expands to empty. |
| 431 | |
| 432 | These macros are useful for marking a function as a potential |
| 433 | portability trap, with the intent that "literal string" include |
| 434 | instructions on the replacement function that should be used |
| 435 | instead. |
| 436 | _GL_WARN_ON_USE is for functions with 'extern' linkage. |
| 437 | _GL_WARN_ON_USE_ATTRIBUTE is for functions with 'static' or 'inline' |
| 438 | linkage. |
| 439 | |
| 440 | However, one of the reasons that a function is a portability trap is |
| 441 | if it has the wrong signature. Declaring FUNCTION with a different |
| 442 | signature in C is a compilation error, so this macro must use the |
| 443 | same type as any existing declaration so that programs that avoid |
| 444 | the problematic FUNCTION do not fail to compile merely because they |
| 445 | included a header that poisoned the function. But this implies that |
| 446 | _GL_WARN_ON_USE is only safe to use if FUNCTION is known to already |
| 447 | have a declaration. Use of this macro implies that there must not |
| 448 | be any other macro hiding the declaration of FUNCTION; but |
| 449 | undefining FUNCTION first is part of the poisoning process anyway |
| 450 | (although for symbols that are provided only via a macro, the result |
| 451 | is a compilation error rather than a warning containing |
| 452 | "literal string"). Also note that in C++, it is only safe to use if |
| 453 | FUNCTION has no overloads. |
| 454 | |
| 455 | For an example, it is possible to poison 'getline' by: |
| 456 | - adding a call to gl_WARN_ON_USE_PREPARE([[#include <stdio.h>]], |
| 457 | [getline]) in configure.ac, which potentially defines |
| 458 | HAVE_RAW_DECL_GETLINE |
| 459 | - adding this code to a header that wraps the system <stdio.h>: |
| 460 | #undef getline |
| 461 | #if HAVE_RAW_DECL_GETLINE |
| 462 | _GL_WARN_ON_USE (getline, "getline is required by POSIX 2008, but" |
| 463 | "not universally present; use the gnulib module getline"); |
| 464 | #endif |
| 465 | |
| 466 | It is not possible to directly poison global variables. But it is |
| 467 | possible to write a wrapper accessor function, and poison that |
| 468 | (less common usage, like &environ, will cause a compilation error |
| 469 | rather than issue the nice warning, but the end result of informing |
| 470 | the developer about their portability problem is still achieved): |
| 471 | #if HAVE_RAW_DECL_ENVIRON |
| 472 | static char *** |
| 473 | rpl_environ (void) { return &environ; } |
| 474 | _GL_WARN_ON_USE (rpl_environ, "environ is not always properly declared"); |
| 475 | # undef environ |
| 476 | # define environ (*rpl_environ ()) |
| 477 | #endif |
| 478 | or better (avoiding contradictory use of 'static' and 'extern'): |
| 479 | #if HAVE_RAW_DECL_ENVIRON |
| 480 | static char *** |
| 481 | _GL_WARN_ON_USE_ATTRIBUTE ("environ is not always properly declared") |
