X-Git-Tag: upstream/2.30~25556 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=3846463e0784dc1315ed07fcc9a604e12012b051;p=external%2Fglibc.git Update. 2000-05-29 Ulrich Drepper * inet/Makefile (CFLAGS-rcmd.c, CFLAGS-rexec.c, CFLAGS-ruserpass.c): Removed. * inet/rcmd.c: Remove __P. Remove unused variables. (iruserfopen): Make first parameter const. (ruserok_sa): Return result of ruserok2_sa. (__checkhost_sa): Correctly iterate through results of getaddrinfo. * inet/rexec.c: Remove unused variables. Other small cleanups. * inet/ruserpass.c: Remove __P. Remove unused variables. (ruserpass): Check results of memory allocation. * include/netdb.h: Add prototype for ruserpass. --- diff --git a/ChangeLog b/ChangeLog index e117190..b85cddf 100644 --- a/ChangeLog +++ b/ChangeLog @@ -1,3 +1,16 @@ +2000-05-29 Ulrich Drepper + + * inet/Makefile (CFLAGS-rcmd.c, CFLAGS-rexec.c, CFLAGS-ruserpass.c): + Removed. + * inet/rcmd.c: Remove __P.
