bc2866336bbb stdio: warn on suspicious uses Eric Blake <ebb9@byu.net> parents: 12600 diff changeset	270 GNU Coding Standards discourage the use of fseek, since it imposes
bc2866336bbb stdio: warn on suspicious uses Eric Blake <ebb9@byu.net> parents: 12600 diff changeset	271 an arbitrary limitation on some 32-bit hosts. Remember that the
bc2866336bbb stdio: warn on suspicious uses Eric Blake <ebb9@byu.net> parents: 12600 diff changeset	272 fseek module depends on the fseeko module, so we only have three
bc2866336bbb stdio: warn on suspicious uses Eric Blake <ebb9@byu.net> parents: 12600 diff changeset	273 cases to consider:
bc2866336bbb stdio: warn on suspicious uses Eric Blake <ebb9@byu.net> parents: 12600 diff changeset	274
bc2866336bbb stdio: warn on suspicious uses Eric Blake <ebb9@byu.net> parents: 12600 diff changeset	275 1. The developer is not using either module. Issue a warning under
bc2866336bbb stdio: warn on suspicious uses Eric Blake <ebb9@byu.net> parents: 12600 diff changeset	276 GNULIB_POSIXCHECK for both functions, to remind them that both
bc2866336bbb stdio: warn on suspicious uses Eric Blake <ebb9@byu.net> parents: 12600 diff changeset	277 functions have bugs on some systems. _GL_NO_LARGE_FILES has no
bc2866336bbb stdio: warn on suspicious uses Eric Blake <ebb9@byu.net> parents: 12600 diff changeset	278 impact on this warning.
bc2866336bbb stdio: warn on suspicious uses Eric Blake <ebb9@byu.net> parents: 12600 diff changeset	279
bc2866336bbb stdio: warn on suspicious uses Eric Blake <ebb9@byu.net> parents: 12600 diff changeset	280 2. The developer is using both modules. They may be unaware of the
bc2866336bbb stdio: warn on suspicious uses Eric Blake <ebb9@byu.net> parents: 12600 diff changeset	281 arbitrary limitations of fseek, so issue a warning under
bc2866336bbb stdio: warn on suspicious uses Eric Blake <ebb9@byu.net> parents: 12600 diff changeset	282 GNULIB_POSIXCHECK. On the other hand, they may be using both
bc2866336bbb stdio: warn on suspicious uses Eric Blake <ebb9@byu.net> parents: 12600 diff changeset	283 modules intentionally, so the developer can define
bc2866336bbb stdio: warn on suspicious uses Eric Blake <ebb9@byu.net> parents: 12600 diff changeset	284 _GL_NO_LARGE_FILES in the compilation units where the use of fseek
bc2866336bbb stdio: warn on suspicious uses Eric Blake <ebb9@byu.net> parents: 12600 diff changeset	285 is safe, to silence the warning.
bc2866336bbb stdio: warn on suspicious uses Eric Blake <ebb9@byu.net> parents: 12600 diff changeset	286
bc2866336bbb stdio: warn on suspicious uses Eric Blake <ebb9@byu.net> parents: 12600 diff changeset	287 3. The developer is using the fseeko module, but not fseek. Gnulib
bc2866336bbb stdio: warn on suspicious uses Eric Blake <ebb9@byu.net> parents: 12600 diff changeset	288 guarantees that fseek will still work around platform bugs in that
bc2866336bbb stdio: warn on suspicious uses Eric Blake <ebb9@byu.net> parents: 12600 diff changeset	289 case, but we presume that the developer is aware of the pitfalls of
bc2866336bbb stdio: warn on suspicious uses Eric Blake <ebb9@byu.net> parents: 12600 diff changeset	290 fseek and was trying to avoid it, so issue a warning even when
bc2866336bbb stdio: warn on suspicious uses Eric Blake <ebb9@byu.net> parents: 12600 diff changeset	291 GNULIB_POSIXCHECK is undefined. Again, _GL_NO_LARGE_FILES can be
bc2866336bbb stdio: warn on suspicious uses Eric Blake <ebb9@byu.net> parents: 12600 diff changeset	292 defined to silence the warning in particular compilation units.
