ACL_DELETE_DEF_FILE(3) BSD Library Functions Manual ACL_DELETE_DEF_FILE(3)NAME
acl_delete_def_file -- delete a default ACL by filename
LIBRARY
Linux Access Control Lists library (libacl, -lacl).
SYNOPSIS
#include <sys/types.h>
#include <sys/acl.h>
int
acl_delete_def_file(const char *path_p);
DESCRIPTION
The acl_delete_def_file() function deletes a default ACL from the directory whose pathname is pointed to by the argument path_p.
The effective user ID of the process must match the owner of the file or directory or the process must have the CAP_FOWNER capability for the
request to succeed.
If the argument path_p is not a directory, then the function fails. It is no error if the directory whose pathname is pointed to by the argu-
ment path_p does not have a default ACL.
RETURN VALUE
The acl_delete_def_file() function returns the value 0 if successful; otherwise the value -1 is returned and the global variable errno is set
to indicate the error.
ERRORS
If any of the following conditions occur, the acl_delete_def_file() function returns the value -1 and and sets errno to the corresponding
value:
[EINVAL] The file referred to by path_p is not a directory.
[ENOTSUP] The file system on which the file identified by path_p is located does not support ACLs, or ACLs are disabled.
[EPERM] The process does not have appropriate privilege to perform the operation to delete the default ACL.
[EROFS] This function requires modification of a file system which is currently read-only.

ACL_GET_FILE(3) BSD Library Functions Manual ACL_GET_FILE(3)NAME
acl_get_file -- get an ACL by filename
LIBRARY
Linux Access Control Lists library (libacl, -lacl).
SYNOPSIS
#include <sys/types.h>
#include <sys/acl.h>
acl_t
acl_get_file(const char *path_p, acl_type_t type);
DESCRIPTION
The acl_get_file() function retrieves the access ACL associated with a file or directory, or the default ACL associated with a directory. The
pathname for the file or directory is pointed to by the argument path_p. The ACL is placed into working storage and acl_get_file() returns a
pointer to that storage.
In order to read an ACL from an object, a process must have read access to the object's attributes.
The value of the argument type is used to indicate whether the access ACL or the default ACL associated with path_p is returned. If type is
ACL_TYPE_ACCESS, the access ACL of path_p is returned. If type is ACL_TYPE_DEFAULT, the default ACL of path_p is returned. If type is
ACL_TYPE_DEFAULT and no default ACL is associated with the directory path_p, then an ACL containing zero ACL entries is returned. If type
specifies a type of ACL that cannot be associated with path_p, then the function fails.
This function may cause memory to be allocated. The caller should free any releasable memory, when the new ACL is no longer required, by
calling acl_free(3) with the (void*)acl_t returned by acl_get_file() as an argument.
RETURN VALUE
Upon successful completion, this function returns a pointer to the working storage. Otherwise, a value of (acl_t)NULL is returned, and errno
is set to indicate the error.
ERRORS
If any of the following conditions occur, the acl_get_file() function returns a value of (acl_t)NULL and sets 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 appro-
priate access rights.
Argument type specifies a type of ACL that cannot be associated with path_p.
[EINVAL] The argument type is not ACL_TYPE_ACCESS or ACL_TYPE_DEFAULT.
[ENAMETOOLONG] The length of the argument path_p is too long.
[ENOENT] The named object does not exist or the argument path_p points to an empty string.
[ENOMEM] The ACL working storage requires more memory than is allowed by the hardware or system-imposed memory management con-
straints.
[ENOTDIR] A component of the path prefix is not a directory.
[ENOTSUP] The file system on which the file identified by path_p is located does not support ACLs, or ACLs are disabled.
