NAME
       dg_allow_shared_descriptor_attach - let processes attach shared
       descriptor array

SYNOPSIS
       #include <sys/types.h>

       int  dg_allow_shared_descriptor_attach (pid_t pid)

   where:
       pid       The process identifier of the process to be given
                 permission to attach.

DESCRIPTION
       Allow the process identified by pid to attach to the shared
       descriptor array of the calling process.  This will enable process
       pid to do a successful dg_attach_to_shared_descriptors(2) on the
       current process.

       The right to attach to a shared descriptor array is inherited across
       forks and execs of process pid.

ACCESS CONTROL
       No access checking is performed.

RETURN VALUE
       0      Process pid may now attach to the shared descriptor array of
              the calling process.

       -1     An error occurred.  errno is set to indicate the error.

DIAGNOSTICS
       Errno may be set to one of the following error codes:

       ESRCH          pid does not exist.
