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. */ | |
