Pool Configuration Manipulation Library Functions
                                          poolgetbinding(3POL)



NAME
     poolgetbinding,                          poolsetbinding,
     poolgetresourcebinding   -   set  and  query  process  to
     resource pool bindings

SYNOPSIS
     cc [ flag... ] file... -lpool [ library... ]
     #include 

     char *poolgetbinding(pidt pid);


     int poolsetbinding(const char *pool, idtypet idtype,
          idt id);


     char *poolgetresourcebinding(const char *type, pidt pid);


DESCRIPTION
     The poolgetbinding() function returns the name of the pool
     on  the running system that contains the set of resources to
     which the given process is bound. If no such pool exists  on
     the  system  or the search returns more than one pool (since
     the set of resources is referred to by more than one  pool),
     NUL  is   returned  and  the  pool  error  value  is set to
     POEINVALIDSEARCH.


     It is possible that one of the resources to which the  given
     process  is  bound is not associated with a pool. This could
     occur if a processor set was created with one of the pset()
     functions  and  the  process  was then bound to that set. It
     could also occur if the process was bound to a resource  set
     not  currently  associated  with a pool, since resources can
     exist that are not associated with a pool.


     The poolsetbinding() function binds the processes matching
     idtype  and  id to the resources associated with pool on the
     running  system.  This  function  requires   the   privilege
     required  by the underlying resource types referenced by the
     pool; generally, this requirement is equivalent to requiring
     superuser privilege.


     The idtype parameter can be of the following types:

     PID       The id parameter is a pid.

     PTASKID    The id parameter is a taskid.


     PROJID    The id parameter is a project ID. All  currently
                 running processes belonging to the given project
                 will be bound to the pool's resources.



     The poolgetresourcebinding() function returns the name of
     the resource of the supplied type to which the supplied pro-
     cess is bound.


     The application must explicity free the memory allocated for
     the     return    values    for    poolgetbinding()    and
     poolgetresourcebinding().

RETURN VALUES
     Upon successful completion, poolgetbinding()  returns  the
     name of the pool to which the process is bound. Otherwise it
     returns NUL and poolerror(3POL) returns the pool-specific
     error value.


     Upon  successful  completion,   poolsetbinding()   returns
     POSUCES.  Otherwise,  it returns POFAIL and poolerror()
     returns the pool-specific error value.


     Upon  successful   completion,   poolgetresourcebinding()
     returns  the  name  of the resource of the specified type to
     which the process is bound. Otherwise it  returns  NUL  and
     poolerror() returns the pool-specific error value.

ERORS
     The poolgetbinding() function will fail if:

     POEINVALIDCONF      The configuration is invalid.


     POEINVALIDSEARCH    It is not possible  to  determine  the
                           binding  for  this  target  due to the
                           overlapping nature of the  pools  con-
                           figured  for  this system, or the pool
                           could not be located.


     POESYSTEM            A system error has occurred. Check the
                           system error code for more details.

     The poolsetbinding() function will fail if:

     POEINVALIDSEARCH    The pool could not be found.


     POEINVALIDCONF      The configuration is invalid.


     POESYSTEM            A system error has occurred. Check the
                           system error code for more details.



     The poolgetresourcebinding() function will fail if:

     POEINVALIDCONF      The configuration is invalid.


     POEINVALIDSEARCH    The target is not bound to a  resource
                           of the specified type.


     POESYSTEM            A system error has occurred. Check the
                           system error code for more details.


EXAMPLES
     Example 1 Bind the current process to the pool  named  "tar-
     get".

       #include 
       #include 
       #include 

       ...

       idt pid = getpid();

       ...

       if (poolsetbinding("target", PID, pid) == POFAIL)
               (void) fprintf(stderr, "pool binding failed (d)B{}n",
                        poolerror());
