NetFileGetInfo2 or Net32FileGetInfo2

The NetFileGetInfo2 API retrieves information about a particular opening of a server resource.

The NetFileGetInfo2 API replaces the NetFileGetInfo API, which is now obsolete.

Restrictions

This API can be called from DLS and OS/2 workstations, but DLS workstations can issue this call only to a remote LAN Server workstation. Administrator authority is required to call this API.

Syntax

 
#include <netcons.h>
#include <shares.h>
 
NetFileGetInfo2(pszServername, fileid, sLevel, buf,
                  usBuflen, pusBytesAvail);     /* 16 bit */
 
Net32FileGetInfo2(pszServername, fileid, ulLevel, buf,
                  ulBuflen, pulBytesAvail);     /* 32 bit */

Parameters

See Common Parameter Definitions for descriptions of parameters not defined here.

fileid

(16-bit unsigned short or 32-bit unsigned long) indicates the identification number assigned to the resource at opening.
sLevel or ulLevel
(16-bit short or 32-bit unsigned long) specifies the level of detail (2 or 3) to be returned by the file_info data structure.

Other codes could be returned from the following functions:

• DosFsCtl
  
• DosGetShrSeg
Remarks

If you call this API with the buffer length parameter equal to zero, the API returns a value for total bytes available. This technique is useful if you do not know the exact buffer size required.
