Remember that the 579 fseek module depends on the fseeko module, so we only have three 580 cases to consider: 581 582 1. The developer is not using either module. Issue a warning under 583 GNULIB_POSIXCHECK for both functions, to remind them that both 584 functions have bugs on some systems. _GL_NO_LARGE_FILES has no 585 impact on this warning. 586 587 2. The developer is using both modules. They may be unaware of the 588 arbitrary limitations of fseek, so issue a warning under 589 GNULIB_POSIXCHECK. On the other hand, they may be using both 590 modules intentionally, so the developer can define 591 _GL_NO_LARGE_FILES in the compilation units where the use of fseek 592 is safe, to silence the warning. 593 594 3. The developer is using the fseeko module, but not fseek. Gnulib 595 guarantees that fseek will still work around platform bugs in that 596 case, but we presume that the developer is aware of the pitfalls of 597 fseek and was trying to avoid it, so issue a warning even when 598 GNULIB_POSIXCHECK is undefined. Again, _GL_NO_LARGE_FILES can be 599 defined to silence the warning in particular compilation units. 600 In C++ compilations with GNULIB_NAMESPACE, in order to avoid that 601 fseek gets defined as a macro, it is recommended that the developer 602 uses the fseek module, even if he is not calling the fseek function. 603 604 Most gnulib clients that perform stream operations should fall into 605 category 3. */ 606 607 #if @GNULIB_FSEEK@ 608 # if defined GNULIB_POSIXCHECK && !defined _GL_NO_LARGE_FILES 609 # define _GL_FSEEK_WARN /* Category 2, above. */ 610 # undef fseek 611 # endif 612 # if @REPLACE_FSEEK@ 613 # if !(defined __cplusplus && defined GNULIB_NAMESPACE) 614 # undef fseek 615 # define fseek rpl_fseek 616 # endif 617 _GL_FUNCDECL_RPL (fseek, int, (FILE *fp, long offset, int whence) 618 _GL_ARG_NONNULL ((1))); 619 _GL_CXXALIAS_RPL (fseek, int, (FILE *fp, long offset, int whence)); 620 # else 621 _GL_CXXALIAS_SYS (fseek, int, (FILE *fp, long offset, int whence)); 622 # endif 623 # if __GLIBC__ >= 2 624 _GL_CXXALIASWARN (fseek); 625 # endif 626 #endif 627 628 #if @GNULIB_FSEEKO@ 629 # if !@GNULIB_FSEEK@ && !defined _GL_NO_LARGE_FILES 630 # define _GL_FSEEK_WARN /* Category 3, above. */ 631 # undef fseek 632 # endif 633 # if @REPLACE_FSEEKO@ 634 /* Provide an fseeko function that is aware of a preceding fflush(), and which 635 detects pipes. */ 636 # if !(defined __cplusplus && defined GNULIB_NAMESPACE) 637 # undef fseeko 638 # define fseeko rpl_fseeko 639 # endif 640 _GL_FUNCDECL_RPL (fseeko, int, (FILE *fp, off_t offset, int whence) 641 _GL_ARG_NONNULL ((1))); 642 _GL_CXXALIAS_RPL (fseeko, int, (FILE *fp, off_t offset, int whence)); 643 # else 644 # if ! @HAVE_DECL_FSEEKO@ 645 _GL_FUNCDECL_SYS (fseeko, int, (FILE *fp, off_t offset, int whence) 646 _GL_ARG_NONNULL ((1))); 647 # endif 648 _GL_CXXALIAS_SYS (fseeko, int, (FILE *fp, off_t offset, int whence)); 649 # endif 650 _GL_CXXALIASWARN (fseeko); 651 #elif defined GNULIB_POSIXCHECK 652 # define _GL_FSEEK_WARN /* Category 1, above. */ 653 # undef fseek 654 # undef fseeko 655 # if HAVE_RAW_DECL_FSEEKO 656 _GL_WARN_ON_USE (fseeko, "fseeko is unportable - " 657 "use gnulib module fseeko for portability"); 658 # endif 659 #endif 660 661 #ifdef _GL_FSEEK_WARN 662 # undef _GL_FSEEK_WARN 663 /* Here, either fseek is undefined (but C89 guarantees that it is 664 declared), or it is defined as rpl_fseek (declared above). */ 665 _GL_WARN_ON_USE (fseek, "fseek cannot handle files larger than 4 GB " 666 "on 32-bit platforms - " 667 "use fseeko function for handling of large files"); 668 #endif 669 670 671 /* ftell, ftello.
