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.
