The Linux kernel uses 'long' instead of 'int' for the return type.
As glibc provides no wrapper, use the same types the kernel uses.

README
This package contains Linux man pages for sections 1 through 8. Some more information is given in the 'man-pages-x.y.Announce' file. Homepage ======== For information about the Linux man-pages project, see http://www.kernel.org/doc/man-pages/index.html. Bug reports and contributing ============================ If you have corrections and additions to suggest, see http://www.kernel.org/doc/man-pages/contributing.html (Although there is a mirror of this repository on GitHub, please don't report issues via the GitHub issue tracker!) For further information on contributing, see the CONTRIBUTING file. Installing and uninstalling =========================== "make install" will copy these man pages to /usr/share/man/man[1-8]. To install to a path different from /usr, use "make install prefix=/install/path". "make remove" or "make uninstall" will remove any man page in this distribution from its destination. Use with caution, and remember to use "prefix" if desired, as with the "install" target. "make" or "make all" will perform "make uninstall" followed by "make install". Copyrights ========== See the 'man-pages-x.y.Announce' file.
