The TMAttribute API call changes the attributes of the file or directory 'fentry' to the attributes 'attribute'. Only the 'name' and 'extension' portions of 'fentry' need be set before calling TMAttribute. See FileEntry for a description of the type. 'attribute' contains bits that are set to apply an attribute and cleared to remove an attribute. 'bit 0' represents the least significant bit in 'attribute'. Here are the attributes for TMEX 3.00:
bit 0 : set to make file read-only, for files only
bit 1 : set to make directory hidden, for directories only
bit 2-7 : reserved for future attributes
For a description of the above types, see the TMEX Type Descriptions.
