FSH_SEGREALLOC - Change segment size

Purpose   

This function changes the size of a segment previously allocated with FSH_ 
SEGALLOC or loaded as part of the FSD image. 

Calling Sequence   

int far pascal FSH_SEGREALLOC(sel, cbSeg)

unsigned short sel;
unsigned long cbSeg;

Where   

sel is the selector to be changed. 

cbSeg is the new size to set for the segment. 
  

Returns   

If no error is detected, a zero error code is returned. If an error is 
detected, one of the following error codes is returned: 

oERROR_NOT_ENOUGH_MEMORY 
too much memory is allocated. 

oERROR_INVALID_ACCESS 
the selector is invalid 
  

Remarks   

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.
