On Fedora this is in the glibc-headers package and it contains many of the commonly used interfaces: $ rpm -qf /usr/include/limits.h glibc-headers-2.13.90-9.x86_64 $ rpm -ql $(rpm -qf /usr/include/limits.h ) | grep \ '/usr/include/[[:alpha:]]*\.h$' | wc -l 100 $ rpm -ql $(rpm -qf /usr/include/limits.h ) | grep \ '/usr/include/[[:alpha:]]*\.h$' /usr/include/aio.h /usr/include/aliases.h /usr/include/alloca.h /usr/include/ar.h [...] /usr/include/utmpx.h /usr/include/values.h /usr/include/wait.h /usr/include/wchar.h /usr/include/wctype.h /usr/include/wordexp.h /usr/include/xlocale.h $ Regards, Bryn. -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines
