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

Syntax

FSH_SEGREALLOC(sel, cbSeg)

Parameters

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:

ERROR_NOT_ENOUGH_MEMORY too much memory is allocated.
ERROR_INVALID_ACCESS the selector is invalid

Calling Sequence

int far pascal FSH_SEGREALLOC(sel, cbSeg)

unsigned short sel;
unsigned long cbSeg;

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.
