door_return(3c)

Standard C Library Functions                                   door_return(3C)



NAME
       door_return - return from a door invocation

SYNOPSIS
       #include <door.h>

       int door_return(char *data_ptr, size_t data_size, door_desc_t *desc_ptr,
            uint_t num_desc);

DESCRIPTION
       The  door_return()  function returns from a door invocation. It returns
       control to the thread that issued the associated door_call() and blocks
       waiting  for  the  next door invocation. See door_call(3C). Results, if
       any, from the door invocation are passed back to the client in the buf‐
       fers  pointed  to  by  data_ptr  and desc_ptr. If there is not a client
       associated with the door_return(),  the  calling  thread  discards  the
       results,   releases   any  passed  descriptors  with  the  DOOR_RELEASE
       attribute, and blocks waiting for the next door invocation.

RETURN VALUES
       Upon successful completion, door_return() does not return to the  call‐
       ing process. Otherwise, door_return() returns −1 to the calling process
       and sets errno to indicate the error.

ERRORS
       The door_return() function fails and returns to the calling process if:

       E2BIG     Arguments were too big for client.


       EFAULT    The address of data_ptr or desc_ptr is invalid.


       EINVAL    Invalid door_return() arguments were passed or  a  thread  is
                 bound to a door that no longer exists.


       EMFILE    The client has too many open descriptors.
