Stage 2 Interfaces

The intent of stage 2 is to use the mini-FSD as an FSD. Therefore, all the 
guidelines and interfaces specified in this document apply with the 
following exceptions. 

The following functions must be fully supported by the mini-FSD: 

oFS_ATTACH (remote mini-FSD only) 
oFS_ATTRIBUTE 
oFS_CHGFILEPTR 
oFS_CLOSE 
oFS_COMMIT 
oFS_INIT 
oFS_IOCTL 
oFS_MOUNT (local mini-FSD only) 
oFS_NAME 
oFS_OPENCREATE (existing file only) 
oFS_PROCESSNAME 
oFS_READ 
  

Note that since the mini-FSD is only required to support reading, FS_ 
OPENCREATE need only support opening an existing file (not the create or 
replace options) . 

None of the other functions required for FSDs are required for the 
mini-FSD but must be defined and should return the 
ERROR_UNSUPPORTED_FUNCTION return code . 

The full complement of helper functions specified in this document is 
available to the mini-FSD. However, the mini-FSD may NOT use any other 
dynamic link calls.
