int pool_set_binding(const char *pool, idtype_t idtype,
id_t id);
char *pool_get_resource_binding(const char *type, pid_t pid);
DESCRIPTION
The pool_get_binding() 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), NULL is returned and the pool error value is set toPOE_INVALID_SEARCH.
It is possible that one of the resources to which the given process is bound is not associated with a pool. This couldoccur 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 pool_set_binding() 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:P_PID The id parameter is a pid.

P_TASKID The id parameter is a taskid.
P_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 pool_get_resource_binding() 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 forthe return values for pool_get_binding() and
pool_get_resource_binding().
RETURN VALUES
Upon successful completion, pool_get_binding() returns the
name of the pool to which the process is bound. Otherwise itreturns NULL and pool_error(3POOL) returns the pool-specific
error value.Upon successful completion, pool_set_binding() returns
PO_SUCCESS. Otherwise, it returns PO_FAIL and pool_error()
returns the pool-specific error value.
Upon successful completion, pool_get_resource_binding()
returns the name of the resource of the specified type to which the process is bound. Otherwise it returns NULL andpool_error() returns the pool-specific error value.
ERRORS
The pool_get_binding() function will fail if:
POE_INVALID_CONF The configuration is invalid.
POE_INVALID_SEARCH It is not possible to determine the
binding for this target due to theoverlapping nature of the pools con-
figured for this system, or the pool could not be located.POE_SYSTEM A system error has occurred. Check the
system error code for more details.SunOS 5.11 Last change: 27 Mar 2007 2

The pool_set_binding() function will fail if:
POE_INVALID_SEARCH The pool could not be found.
POE_INVALID_CONF The configuration is invalid.
POE_SYSTEM A system error has occurred. Check the
system error code for more details.The pool_get_resource_binding() function will fail if:
POE_INVALID_CONF The configuration is invalid.
POE_INVALID_SEARCH The target is not bound to a resource
of the specified type.POE_SYSTEM A system error has occurred. Check the

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

#include
...id_t pid = getpid();
...if (pool_set_binding("target", P_PID, pid) == PO_FAIL)
(void) fprintf(stderr, "pool binding failed (d)B{}n",pool_error());
