Door Interface Revisions

This developer tool enhancement is new in the Solaris Express 6/05 release.

Two new functions, door_setparam and door_getparam, have been added to the doors interfaces. These functions enable door servers to set boundaries on the data size and on the number of descriptors that are passed to door_call on the door. These enhancements simplify the door's handler function.

The door_create interface has a new flag, DOOR_NO_CANCEL. This flag disables the cancellation process of the server thread when the client aborts a door_call function due to a signal. For door servers which do not take advantage of cancellation, this change can prevent unwanted EINTR returns from interrupted system calls.

For more information, see the door_setparam(3C) and door_create(3C) man pages.
