NAME
       pool_walk_components, pool_walk_pools, pool_walk_resources - walk objects within resource pool configurations

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

       int  pool_walk_components(pool_conf_t  *conf,  pool_resource_t *resource, void *arg, int (*callback)(pool_conf_t *, pool_resource_t *, void
       *));

       int pool_walk_pools(pool_conf_t *conf, void *arg, int (*callback)(pool_conf_t *, pool_component_t *, void *));

       int pool_walk_resources(pool_conf_t *conf, pool_t *pool, void *arg, int (*callback)(pool_conf_t *, pool_component_t *, void *));

       The walker functions provided with libpool(3LIB) visit each associated entity of the given type,  and  call  the  caller-provided  callback
       function  with  a user-provided additional opaque argument. There is no implied order of visiting nodes in the walk.  If the callback func-
       tion returns a non-zero value at any of the nodes, the walk is terminated, and an error value of -1 returned. The conf  argument  for  each
       function refers to the target configuration to which the operation applies.

       The pool_walk_components() function invokes callback on all components contained in the resource.

       The pool_walk_pools() function invokes callback on all pools defined in the configuration.

       The pool_walk_resources() function invokes callback function on all resources associated with pool.

       Upon  successful completion of the walk, these functions return 0. Otherwise -1 is returned and pool_error(3POOL) returns the pool-specific
       error value.

       These functions will fail if:

       POE_BADPARAM	       The supplied configuration's status is not POF_VALID.

       POE_INVALID_CONF        The configuration is invalid.

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