This is part of Family API which allow to create dual-os version of program runs under OS/2 and DOS

Note: This is legacy API call. It is recommended to use 32-bit equivalent

DosQFileMode

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

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.

Return Code

rc (USHORT) - return

Return code descriptions are:

0 NO_ERROR

2 ERROR_FILE_NOT_FOUND

3 ERROR_PATH_NOT_FOUND

26 ERROR_NOT_DOS_DISK

87 ERROR_INVALID_PARAMETER

108 ERROR_DRIVE_LOCKED

206 ERROR_FILENAME_EXCED_RANGE

Remarks

The “Volume Label” type attribute is not returned by DosQFileMode. DosQFSInfo may be used for this purpose.

Example Code

C Binding

#define INCL_DOSFILEMGR USHORT rc = DosQFileMode(FilePathName, CurrentAttribute, Reserved); PSZ FilePathName; /* File path name */ PUSHORT CurrentAttribute; /* Data area (returned) */ ULONG 0; /* Reserved (must be zero) */ USHORT rc; /* return code */

MASM Binding

EXTRN DosQFileMode:FAR INCL_DOSFILEMGR EQU 1 PUSH@ ASCIIZ FilePathName ;File path name PUSH@ WORD CurrentAttribute ;Data area (returned) PUSH DWORD 0 ;Reserved (must be zero) CALL DosQFileMode

Returns WORD
