| 474 | /* Set up the following warnings, based on which modules are in use. |
| 475 | GNU Coding Standards discourage the use of fseek, since it imposes |
| 476 | an arbitrary limitation on some 32-bit hosts. Remember that the |
| 477 | fseek module depends on the fseeko module, so we only have three |
| 478 | cases to consider: |
| 479 | |
| 480 | 1. The developer is not using either module. Issue a warning under |
| 481 | GNULIB_POSIXCHECK for both functions, to remind them that both |
| 482 | functions have bugs on some systems. _GL_NO_LARGE_FILES has no |
| 483 | impact on this warning. |
| 484 | |
| 485 | 2. The developer is using both modules. They may be unaware of the |
| 486 | arbitrary limitations of fseek, so issue a warning under |
| 487 | GNULIB_POSIXCHECK. On the other hand, they may be using both |
| 488 | modules intentionally, so the developer can define |
| 489 | _GL_NO_LARGE_FILES in the compilation units where the use of fseek |
| 490 | is safe, to silence the warning. |
| 491 | |
| 492 | 3. The developer is using the fseeko module, but not fseek. Gnulib |
| 493 | guarantees that fseek will still work around platform bugs in that |
| 494 | case, but we presume that the developer is aware of the pitfalls of |
| 495 | fseek and was trying to avoid it, so issue a warning even when |
| 496 | GNULIB_POSIXCHECK is undefined. Again, _GL_NO_LARGE_FILES can be |
| 497 | defined to silence the warning in particular compilation units. |
| 498 | In C++ compilations with GNULIB_NAMESPACE, in order to avoid that |
| 499 | fseek gets defined as a macro, it is recommended that the developer |
| 500 | uses the fseek module, even if he is not calling the fseek function. |
| 501 | |
| 502 | Most gnulib clients that perform stream operations should fall into |
| 503 | category 3. */ |
