420 | /* Set up the following warnings, based on which modules are in use. |
421 | GNU Coding Standards discourage the use of fseek, since it imposes | |
422 | an arbitrary limitation on some 32-bit hosts. Remember that the | |
423 | fseek module depends on the fseeko module, so we only have three | |
424 | cases to consider: | |
425 | ||
426 | 1. The developer is not using either module. Issue a warning under | |
427 | GNULIB_POSIXCHECK for both functions, to remind them that both | |
428 | functions have bugs on some systems. _GL_NO_LARGE_FILES has no | |
429 | impact on this warning. | |
430 | ||
431 | 2. The developer is using both modules. They may be unaware of the | |
432 | arbitrary limitations of fseek, so issue a warning under | |
433 | GNULIB_POSIXCHECK. On the other hand, they may be using both | |
434 | modules intentionally, so the developer can define | |
435 | _GL_NO_LARGE_FILES in the compilation units where the use of fseek | |
436 | is safe, to silence the warning. | |
437 | ||
438 | 3. The developer is using the fseeko module, but not fseek. Gnulib | |
439 | guarantees that fseek will still work around platform bugs in that | |
440 | case, but we presume that the developer is aware of the pitfalls of | |
441 | fseek and was trying to avoid it, so issue a warning even when | |
442 | GNULIB_POSIXCHECK is undefined. Again, _GL_NO_LARGE_FILES can be | |
443 | defined to silence the warning in particular compilation units. | |
f4c79b3c LC |
444 | In C++ compilations with GNULIB_NAMESPACE, in order to avoid that |
445 | fseek gets defined as a macro, it is recommended that the developer | |
446 | uses the fseek module, even if he is not calling the fseek function. | |
