ATTR_REMOVE(3)						       XFS Compatibility API						    ATTR_REMOVE(3)

NAME

       attr_remove, attr_removef - remove a user attribute of a filesystem object

C SYNOPSIS

       #include <attr/attributes.h>

       int attr_remove (const char *path, const char *attrname, int flags);

       int attr_removef (int fd, const char *attrname, int flags);

DESCRIPTION

       The attr_remove and attr_removef functions provide a way to remove previously created attributes from filesystem objects.

       Path points to a path name for a filesystem object, and fd refers to the file descriptor associated with a file.  If the attribute attrname
       exists, the attribute name and value will be removed from the fileystem object.	The flags argument can contain the following symbols  bit-
       wise OR'ed together:

       ATTR_ROOT
	      Look for attrname in the root address space, not in the user address space.  (limited to use by super-user only)

       ATTR_DONTFOLLOW
	      Do not follow symbolic links when resolving a path on an attr_remove function call.  The default is to follow symbolic links.

       attr_remove will fail if one or more of the following are true:

       [ENOATTR]	The attribute name given is not associated with the indicated filesystem object.

       [ENOENT] 	The named file does not exist.

       [EPERM]		The effective user ID does not match the owner of the file and the effective user ID is not super-user.

       [ENOTDIR]	A component of the path prefix is not a directory.

       [EACCES] 	Search permission is denied on a component of the path prefix.

       [EINVAL] 	A bit was set in the flag argument that is not defined for this system call.

       [EFAULT] 	Path points outside the allocated address space of the process.

       [ELOOP]		A path name lookup involved too many symbolic links.

       [ENAMETOOLONG]	The length of path exceeds {MAXPATHLEN}, or a pathname component is longer than {MAXNAMELEN}.

       attr_removef will fail if:

       [ENOATTR]      The attribute name given is not associated with the indicated filesystem object.

       [EINVAL]       A bit was set in the flag argument that is not defined for this system call, or fd refers to a socket, not a file.

       [EFAULT]       Attrname points outside the allocated address space of the process.

       [EBADF]	      Fd does not refer to a valid descriptor.

DIAGNOSTICS

       Upon successful completion, a value of 0 is returned.  Otherwise, a value of -1 is returned and errno is set to indicate the error.
