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