FSH_GETVOLPARM - Get VPB data from VPB handle

Purpose   

This function allows an FSD to retrieve file-system-independent and file- 
system-dependent data from a VPB. Since the FS router passes in a VPB 
handle, individual FSDs need to map the handle into pointers to the 
relevant portions. 

Calling Sequence   

void far pascal FSH_GETVOLPARM(hVPB, ppVPBfsi, ppVPBfsd)

unsigned short hVPB;
struc vpfsi far * far * ppVPBfsi;
struc vpfsd far * far * ppVPBfsd;

Where   

hVPB is the volume handle of interest. 

ppVPBfsi indicates the location where the pointer to 
file-system-independent data is stored. 

ppVPBfsd indicates the location where the pointer to file-system-dependent 
data is stored. 
  

Returns   

There are no error returns. 

Remarks   

FSH_GETVOLPARM will not block. 

Note:   OS/2 does not validate input parameters. An FSD, therefore, should 
call FSH_PROBEBUF where appropriate.
