#include <dpmi.h> int _go32_dpmi_allocate_iret_wrapper(_go32_dpmi_seginfo *info);
See section DPMI Overview
This function creates a small assembler function that handles the
overhead of servicing an interrupt. To use, put the address of your
servicing function in the pm_offset
field of info and call
this function. The pm_field
will get replaced with the address
of the wrapper function, which you pass to both
_go32_dpmi_set_protected_mode_interrupt_vector
and
_go32_dpmi_free_iret_wrapper
.
See section _go32_dpmi_set_protected_mode_interrupt_vector See section _go32_dpmi_free_iret_wrapper
Zero on success, nonzero on failure.
