Getting and setting attributes z/OS UNIX System Services File System Interface Reference SA23-2285-00 |
|
A file's attributes are returned by the v_getattr() function. Many of the other VFS callable services API functions also return file attributes as a performance enhancement, since attributes are often requested in conjunction with those functions. A file's attributes are changed with the v_setattr() function. A set of "change bits" are used on this interface, and the VFS server specifies exactly which attributes are being updated, along with the new values for those attributes. |
