Syntax

#include <dpmi.h> int __dpmi_set_segment_limit(int _selector, unsigned _address);

Description

Please refer to the DPMI Specification (see section DPMI Specification) for details on DPMI function call operation. Also see the DPMI Overview (see section DPMI Overview) for general information.

DPMI function AX = 0x0008

This function sets the highest valid address in the segment referenced by _selector. For example, if you pass 0xfffff, the highest valid address is 0xfffff. Note: if you pass a number <= 64K, the segment changes to "non-big", and may cause unexpected problems. Limits for segments larger than 1MB must have their low 12 bits set.

Return Value

-1 on error, else zero.
