- 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 reponsible 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.

The pool_component_info() function will fail if:

POE_BADPARAM
