412 GNU Coding Standards discourage the use of fseek, since it imposes
413 an arbitrary limitation on some 32-bit hosts. Remember that the
414 fseek module depends on the fseeko module, so we only have three
415 cases to consider:
416
417 1. The developer is not using either module. Issue a warning under
418 GNULIB_POSIXCHECK for both functions, to remind them that both
419 functions have bugs on some systems. _GL_NO_LARGE_FILES has no
420 impact on this warning.
421
422 2. The developer is using both modules. They may be unaware of the
423 arbitrary limitations of fseek, so issue a warning under
424 GNULIB_POSIXCHECK. On the other hand, they may be using both
425 modules intentionally, so the developer can define
426 _GL_NO_LARGE_FILES in the compilation units where the use of fseek
427 is safe, to silence the warning.
428
429 3. The developer is using the fseeko module, but not fseek. Gnulib
430 guarantees that fseek will still work around platform bugs in that
431 case, but we presume that the developer is aware of the pitfalls of
432 fseek and was trying to avoid it, so issue a warning even when
433 GNULIB_POSIXCHECK is undefined. Again, _GL_NO_LARGE_FILES can be
434 defined to silence the warning in particular compilation units.
f4c79b3c
LC		 435 In C++ compilations with GNULIB_NAMESPACE, in order to avoid that
436 fseek gets defined as a macro, it is recommended that the developer
437 uses the fseek module, even if he is not calling the fseek function.
