acl_delete_def_file man page
acl_delete_def_file — delete a default ACL by filename
Linux Access Control Lists library (libacl, -lacl).
acl_delete_def_file(const char *path_p);
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 argument path_p does not have a default ACL.
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.
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:
- The file referred to by path_p is not a directory.
- The file system on which the file identified by path_p is located does not support ACLs, or ACLs are disabled.
- The process does not have appropriate privilege to perform the operation to delete the default ACL.
- This function requires modification of a file system which is currently read-only.
