FSH_CALLDRIVER - Call Device Driver's Extended Strategy entry point
This routine allows FSDs to call a device driver's Extended Strategy entry
int far pascal FSH_CALLDRIVER(pPkt, hVPB, fControl)
void far * pPkt;
unsigned short hVPB;
unsigned short fControl;
pPkt is a pointer to device driver Extended strategy request packet.
hVPB is the volume handle for the source of I/O.
fControl is the bit mask of pop-up control actions:
Bit 0 off indicates volume change pop-up desired
Bit 0 on indicates no volume change pop-up
All other bits are reserved and must be zero.
If no error is detected, a zero error code is returned. If an error is
detected, one of the following error codes is returned:
is an indication that removable media volume change has occurred.
the fControl flag word has reserved bits on.
This routine should be called for any Extended strategy requests going to
a drive that has removable media.
For a detailed description of the Extended Strategy request interface
please see the OS/2 Version 2.0 Physical Device Driver Reference
FSH_CALLDRIVER may block.
Note: OS/2 does not validate input parameters. Therefore, an FSD should
call FSH_PROBEBUF where appropriate.
