From 0d83b42e2d59b722a66c7e3fed50437a647ed4ee Mon Sep 17 00:00:00 2001 From: Roland McGrath Date: Wed, 16 Oct 2002 22:09:42 +0000 Subject: 2002-10-16 Roland McGrath * sysdeps/unix/sysv/linux/fpathconf.c (LINUX_LINK_MAX): Move macro ... * sysdeps/unix/sysv/linux/linux_fsinfo.h (LINUX_LINK_MAX): ... here. * sysdeps/unix/sysv/linux/pathconf.h: New file. (statfs_link_max): New function, guts from fpathconf.c. * sysdeps/unix/sysv/linux/fpathconf.c: Rewritten using that. * sysdeps/unix/sysv/linux/pathconf.c (__pathconf): Likewise. * sysdeps/unix/sysv/linux/alpha/pathconf.c (__pathconf): Rewritten to use the linux/pathconf.c code by #include rather than duplication. * sysdeps/unix/sysv/linux/alpha/fpathconf.c (__pathconf): Likewise. --- sysdeps/unix/sysv/linux/fpathconf.c | 69 ++++--------------------------------- 1 file changed, 7 insertions(+), 62 deletions(-) (limited to 'sysdeps/unix/sysv/linux/fpathconf.c') diff --git a/sysdeps/unix/sysv/linux/fpathconf.c b/sysdeps/unix/sysv/linux/fpathconf.c index 108ffa705a..a43a58767d 100644 --- a/sysdeps/unix/sysv/linux/fpathconf.c +++ b/sysdeps/unix/sysv/linux/fpathconf.c @@ -1,4 +1,4 @@ -/* Linux specific extensions to fpathconf. +/* Get file-specific information about descriptor FD.
