Calling Sequence   

int far pascal FSH_SEGREALLOC(sel, cbSeg)

unsigned short sel;
unsigned long cbSeg;

sel is the selector to be changed. 
cbSeg is the new size to set for the segment. 
If no error is detected, a zero error code is returned. If an error is 
detected, one of the following error codes is returned: 
too much memory is allocated. 
the selector is invalid 
The segment may be grown or shrunk. The segment may be moved in the 
process. When grown, the extra space is uninitialized. 
FSH_SEGREALLOC may block. 
Note:   OS/2 does not validate input parameters. An FSD, therefore, should 
call FSH_PROBEBUF where appropriate.
