ACL_GET_FILE (3) 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
On success, this function returns a pointer to the working storage. On error, a value of (acl_t)NULL is returned, and errno is set appropriately.
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 appropriate 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 constraints.
[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.
