576 | /* Set up the following warnings, based on which modules are in use. | |
577 | GNU Coding Standards discourage the use of fseek, since it imposes | |
578 | an arbitrary limitation on some 32-bit hosts. Remember that the | |
579 | fseek module depends on the fseeko module, so we only have three | |
580 | cases to consider: | |
581 | ||
582 | 1. The developer is not using either module. Issue a warning under | |
583 | GNULIB_POSIXCHECK for both functions, to remind them that both | |
584 | functions have bugs on some systems. _GL_NO_LARGE_FILES has no | |
585 | impact on this warning. | |
586 | ||
587 | 2. The developer is using both modules. They may be unaware of the | |
588 | arbitrary limitations of fseek, so issue a warning under | |
589 | GNULIB_POSIXCHECK. On the other hand, they may be using both | |
590 | modules intentionally, so the developer can define | |
591 | _GL_NO_LARGE_FILES in the compilation units where the use of fseek | |
592 | is safe, to silence the warning. | |
593 | ||
594 | 3. The developer is using the fseeko module, but not fseek. Gnulib | |
595 | guarantees that fseek will still work around platform bugs in that | |
596 | case, but we presume that the developer is aware of the pitfalls of | |
597 | fseek and was trying to avoid it, so issue a warning even when | |
598 | GNULIB_POSIXCHECK is undefined. Again, _GL_NO_LARGE_FILES can be | |
599 | defined to silence the warning in particular compilation units. | |
600 | In C++ compilations with GNULIB_NAMESPACE, in order to avoid that | |
601 | fseek gets defined as a macro, it is recommended that the developer | |
602 | uses the fseek module, even if he is not calling the fseek function. | |
603 | ||
604 | Most gnulib clients that perform stream operations should fall into | |
605 | category 3. */ | |
