Description |
The FileSetAttr function sets the attributes of the specified FileName.
The Attributes integer must be set to a combination of none, some or all of the following independent bit settings :
faReadOnly | : 1 : Read-only files |
faHidden | : 2 : Hidden files |
faSysFile | : 4 : System files |
faVolumeID | : 8 : Volume ID files |
faDirectory | : 16 : Directory files |
faArchive | : 32 : Archive files |
faSymLink | : 64 : Symbolic link |
The returned Integer value is zero if the set was successful, otherwise it contains an error code.
|
|
Notes |
This function is Operating System dependent. For example, Archive means nothing on Linux.
Important : During testing, the author always received a non-zero return code, even though the appropriate bits were set OK.
