 POOL_COMPONENT_INFO 3POOL "April 9, 2016"
 NAME
pool_component_info, pool_get_owning_resource - resource pool component
functions
 SYNOPSIS

cc [ flag.\|.\|. ] file.\|.\|. -lpool [ library.\|.\|. ]
#include <pool.h>

const char *pool_component_info(pool_conf_t *conf,
 pool_component_t *component, int flags);


pool_resource_t *pool_get_owning_resource(pool_conf_t *conf,
 pool_component_t *component);


 DESCRIPTION

Certain resources, such as processor sets, are composed of resource components.
Informational and ownership attributes of resource components are made
available with the pool_component_info() and
pool_get_owning_resource() functions. The conf argument for each
function refers to the target configuration to which the operation applies.

The pool_component_info() function returns a string describing
component. The string is allocated with malloc(3C). The caller is
responsible for freeing the returned string. The flags argument is
ignored.

The pool_get_owning_resource() function returns the resource currently
containing component. Every component is contained by a resource.
 RETURN VALUES

Upon successful completion, pool_component_info() returns a string.
Otherwise it returns NULL and pool_error(3POOL) returns the
pool-specific error value.

Upon successful completion, pool_get_owning_resource() returns the owning
resource. Otherwise it returns NULL and pool_error() returns the
pool-specific error value.
 ERRORS

The pool_component_info() function will fail if:
POE_BADPARAM

The supplied configuration's status is not POF_VALID or the flags
paramter is neither 0 or 1.


POE_INVALID_CONF

POE_SYSTEM

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