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 bitwise 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.
