DosQFileMode

This call queries the mode (attribute) of the specified file.

This function has been renamed to "DosQueryFileMode".

Syntax

DosQFileMode (FilePathName, CurrentAttribute, Reserved) 

Parameters

FilePathName (PSZ) - input

Address of the file path name.

DosQSysInfo is called by an application during initialization to determine the maximum path length allowed by OS/2.

CurrentAttribute (PUSHORT) - output

Address of the file's current attribute.

Bit        Description
15-6        Reserved.
5        File archive 
4        Subdirectory 
3        Reserved
2        System file
1        Hidden file
0        Read only file

These bits can be set individually or in combination. For example, an attribute value of 0021H (bits 5 and 0 set to 1) indicates a read-only file that is archived.

Reserved (ULONG) - input

Reserved must be set to zero.
