NAME

       door_return - return from a door invocation

SYNOPSIS

       cc -mt [ flag ... ] file ... -ldoor  [ library ... ]
       #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(3DOOR).  Results, if any, from the door  invocation  are  passed  back   to  the
       client  in  the buffers 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 calling 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.
