Since glibc and musl libc are now two libcs with supposedly the same API, it's useful to be able to reference the common specification behind this API. Beyond POSIX, it is the LSB.
Also some of the API (e.g. dl_iterate_phdr) is found on BSD systems as well, but not specified by POSIX. Therefore it makes sense to add references to the LSB where available. 2020-11-22 Bruno Haible <br...@clisp.org> doc: Add references to the LSB. * doc/glibc-functions/*.texi: Add references to LSB 5.0. * doc/posix-functions/*.texi: Likewise. https://git.savannah.gnu.org/gitweb/?p=gnulib.git;a=commitdiff;h=070535708ddf0a0105ef996be4a453fe0c749673
