452: /* Set up the following warnings, based on which modules are in use.
453: GNU Coding Standards discourage the use of fseek, since it imposes
454: an arbitrary limitation on some 32-bit hosts. Remember that the
455: fseek module depends on the fseeko module, so we only have three
456: cases to consider:
457:
458: 1. The developer is not using either module. Issue a warning under
459: GNULIB_POSIXCHECK for both functions, to remind them that both
460: functions have bugs on some systems. _GL_NO_LARGE_FILES has no
461: impact on this warning.
462:
463: 2. The developer is using both modules. They may be unaware of the
464: arbitrary limitations of fseek, so issue a warning under
465: GNULIB_POSIXCHECK. On the other hand, they may be using both
466: modules intentionally, so the developer can define
467: _GL_NO_LARGE_FILES in the compilation units where the use of fseek
468: is safe, to silence the warning.
469:
470: 3. The developer is using the fseeko module, but not fseek. Gnulib
471: guarantees that fseek will still work around platform bugs in that
472: case, but we presume that the developer is aware of the pitfalls of
473: fseek and was trying to avoid it, so issue a warning even when
474: GNULIB_POSIXCHECK is undefined. Again, _GL_NO_LARGE_FILES can be
475: defined to silence the warning in particular compilation units.
476: In C++ compilations with GNULIB_NAMESPACE, in order to avoid that
477: fseek gets defined as a macro, it is recommended that the developer
478: uses the fseek module, even if he is not calling the fseek function.
479:
