attr_remove(3) [bsd man page]

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
On success, zero is returned. On error, -1 is returned, and errno is set appropriately. SEE ALSO
attr(1), attr_get(3), attr_list(3), attr_multi(3), and attr_set(3). Dec 2001 Extended Attributes ATTR_REMOVE(3)
