All uses replaced by char *. + * xgetcwd.c: David MacKenzie's old code was removed, so give + credit only to Jim Meyering and adjust the copyright dates. + Do not include <limits.h>, <stdio.h>, <sys/types.h>, + <stdlib.h>, <unistd.h>, "pathmax.h". + Instead, include "xgetcwd.h" (first) and "getcwd.h". + (INITIAL_BUFFER_SIZE): Remove. + (xgetcwd): Rely on getcwd, since we now depend on a reliable one. + 2004-11-23 Paul Eggert <eggert@cs.ucla.edu> * utimens.c (__attribute__, ATTRIBUTE_UNUSED): New macros. |
