NAME
pool_get_pool, pool_get_resource, pool_query_components, pool_query_pools, pool_query_resources - retrieve resource pool configuration ele- ments SYNOPSIS
cc [ flag]... file... -lpool [ library... ] #include <pool.h> pool_t *pool_get_pool(pool_conf_t *conf, const char *name); pool_resource_t *pool_get_resource(pool_conf_t *conf const char *type, const char *name); pool_component_t **pool_query_components(pool_conf_t *conf, uint_t *nelem, pool_value_t **props); pool_t **pool_query_pools(pool_conf_t *conf, uint_t *nelem, pool_value_t **props); pool_component_t **pool_query_resources(pool_conf_t *conf, uint_t *nelem, pool_value_t **props); DESCRIPTION
These functions provide a means for querying the contents of the specified configuration. The conf argument for each function refers to the target configuration to which the operation applies. The pool_get_pool() function returns the pool with the given name from the provided configuration. The pool_get_resource() function returns the resource with the given name and type from the provided configuration. The pool_query_components() function retrieves all resource components that match the given list of properties. If the list of properties is NULL, all components are returned. The number of elements returned is stored in the location pointed to by nelem. The value returned by pool_query_components() is allocated with malloc(3C) and must be explicitly freed. The pool_query_pools() function behaves similarly to pool_query_components() and returns the list of pools that match the given list of properties. The value returned must be freed by the caller. The pool_query_resources() function similarly returns the list of resources that match the given list of properties. The return value must be freed by the caller. RETURN VALUES
The pool_get_pool() and pool_get_resource() functions return the matching pool and resource, respectively. Otherwise, they return NULL and pool_error(3POOL) returns the pool-specific error value. The pool_query_components(), pool_query_pools(), and pool_query_resources() functions return a null-terminated array of components, pools, and resources, respectively. If the query was unsuccessful or there were no matches, NULL is returned and pool_error() returns the pool- specific error value. ERRORS
The pool_get_pool() will fail if: POE_BADPARAM The supplied configuration's status is not POF_VALID. The pool_get_resource() will fail if: POE_BADPARAM The supplied configuration's status is not POF_VALID. POE_SYSTEM There is not enough memory available to allocate working buffers. Check errno for the specific system error code. The pool_query_components(), pool_query_pools(), and pool_query_resources() will fail if: POE_BADPARAM The supplied configuration's status is not POF_VALID. POE_INVALID_CONF The query generated results that were not of the correct type. The configuration is invalid. POE_SYSTEM There is not enough memory available to allocate working buffers. Check errno for the specific system error code. EXAMPLES
Example 1 Retrieve the pool named "foo" from a given configuration. #include <pool.h> #include <stdio.h> ... pool_conf_t *conf; pool_t *pool; ... if ((pool = pool_get_pool(conf, "foo")) == NULL) { (void) fprintf(stderr, "Cannot retrieve pool named 'foo'0 ... } ATTRIBUTES
