Remember that the 731 fseek module depends on the fseeko module, so we only have three 732 cases to consider: 733 734 1. The developer is not using either module. Issue a warning under 735 GNULIB_POSIXCHECK for both functions, to remind them that both 736 functions have bugs on some systems. _GL_NO_LARGE_FILES has no 737 impact on this warning. 738 739 2. The developer is using both modules. They may be unaware of the 740 arbitrary limitations of fseek, so issue a warning under 741 GNULIB_POSIXCHECK. On the other hand, they may be using both 742 modules intentionally, so the developer can define 743 _GL_NO_LARGE_FILES in the compilation units where the use of fseek 744 is safe, to silence the warning. 745 746 3. The developer is using the fseeko module, but not fseek. Gnulib 747 guarantees that fseek will still work around platform bugs in that 748 case, but we presume that the developer is aware of the pitfalls of 749 fseek and was trying to avoid it, so issue a warning even when 750 GNULIB_POSIXCHECK is undefined. Again, _GL_NO_LARGE_FILES can be 751 defined to silence the warning in particular compilation units. 752 In C++ compilations with GNULIB_NAMESPACE, in order to avoid that 753 fseek gets defined as a macro, it is recommended that the developer 754 uses the fseek module, even if he is not calling the fseek function. 755 756 Most gnulib clients that perform stream operations should fall into 757 category 3. */ 758 759 #if 0 760 # if defined GNULIB_POSIXCHECK && !defined _GL_NO_LARGE_FILES 761 # define _GL_FSEEK_WARN /* Category 2, above. */ 762 # undef fseek 763 # endif 764 # if 0 765 # if !(defined __cplusplus && defined GNULIB_NAMESPACE) 766 # undef fseek 767 # define fseek rpl_fseek 768 # endif 769 _GL_FUNCDECL_RPL (fseek, int, (FILE *fp, long offset, int whence) 770 _GL_ARG_NONNULL ((1))); 771 _GL_CXXALIAS_RPL (fseek, int, (FILE *fp, long offset, int whence)); 772 # else 773 _GL_CXXALIAS_SYS (fseek, int, (FILE *fp, long offset, int whence)); 774 # endif 775 _GL_CXXALIASWARN (fseek); 776 #endif 777 778 #if 0 779 # if !0 && !defined _GL_NO_LARGE_FILES 780 # define _GL_FSEEK_WARN /* Category 3, above. */ 781 # undef fseek 782 # endif 783 # if 0 784 /* Provide an fseeko function that is aware of a preceding fflush(), and which 785 detects pipes. */ 786 # if !(defined __cplusplus && defined GNULIB_NAMESPACE) 787 # undef fseeko 788 # define fseeko rpl_fseeko 789 # endif 790 _GL_FUNCDECL_RPL (fseeko, int, (FILE *fp, off_t offset, int whence) 791 _GL_ARG_NONNULL ((1))); 792 _GL_CXXALIAS_RPL (fseeko, int, (FILE *fp, off_t offset, int whence)); 793 # else 794 # if ! 1 795 _GL_FUNCDECL_SYS (fseeko, int, (FILE *fp, off_t offset, int whence) 796 _GL_ARG_NONNULL ((1))); 797 # endif 798 _GL_CXXALIAS_SYS (fseeko, int, (FILE *fp, off_t offset, int whence)); 799 # endif 800 _GL_CXXALIASWARN (fseeko); 801 #elif defined GNULIB_POSIXCHECK 802 # define _GL_FSEEK_WARN /* Category 1, above. */ 803 # undef fseek 804 # undef fseeko 805 # if HAVE_RAW_DECL_FSEEKO 806 _GL_WARN_ON_USE (fseeko, "fseeko is unportable - " 807 "use gnulib module fseeko for portability"); 808 # endif 809 #endif 810 811 #ifdef _GL_FSEEK_WARN 812 # undef _GL_FSEEK_WARN 813 /* Here, either fseek is undefined (but C89 guarantees that it is 814 declared), or it is defined as rpl_fseek (declared above). */ 815 _GL_WARN_ON_USE (fseek, "fseek cannot handle files larger than 4 GB " 816 "on 32-bit platforms - " 817 "use fseeko function for handling of large files"); 818 #endif 819 820 821 /* ftell, ftello.
