NAME

door_return - return from a door invocation
 

SYNOPSIS

cc -mt [ flag... ] file... [ 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(3C). 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.
