LIBRARY


.Lb libc

SYNOPSIS


.In sys/types.h
.In sys/acl.h int acl_delete_def_file "const char *path_p" int acl_delete_def_link_np "const char *path_p" int acl_delete_fd_np "int filedes" "acl_type_t type" int acl_delete_file_np "const char *path_p" "acl_type_t type" int acl_delete_link_np "const char *path_p" "acl_type_t type"

DESCRIPTION

The acl_delete_def_file, acl_delete_def_link_np, acl_delete_fd_np, acl_delete_file_np, and acl_delete_link_np each allow the deletion of an ACL from a file. The acl_delete_def_file function is a POSIX.1e call that deletes the default ACL from a file (normally a directory) by name; the remainder of the calls are non-portable extensions that permit the deletion of arbitrary ACL types from a file/directory either by path name or file descriptor. The _file variations follow a symlink if it occurs in the last segment of the path name; the _link variations operate on the symlink itself.

IMPLEMENTATION NOTES


.Fx Ns ’s support for POSIX.1e interfaces and features is still under development at this time.

RETURN VALUES


.Rv -std

ERRORS

If any of the following conditions occur, these functions shall return -1 and set errno to the corresponding value:
[EACCES]
Search permission is denied for a component of the path prefix, or the object exists and the process does not have appropriate access rights.
[EBADF]
The fd argument is not a valid file descriptor.
[EINVAL]
The ACL type passed is invalid for this file object.
[ENAMETOOLONG]
A component of a pathname exceeded 255 characters, or an entire path name exceeded 1023 characters.
[ENOENT]
The named object does not exist, or the path_p argument points to an empty string.
[ENOMEM]
Insufficient memory available to fulfill request.
[ENOTDIR]
A component of the path prefix is not a directory.

Argument path_p must be a directory, and is not.

[EOPNOTSUPP]
The file system does not support ACL deletion.
[EPERM]
The process does not have appropriate privilege to perform the operation to delete an ACL.
[EROFS]
The file system is read-only.
