NAME
pool_dynamic_location, pool_static_location, pool_version,
pool_get_status, pool_set_status, pool_resource_type_list - resource
pool framework functions
SYNOPSIS
cc [ flag... ] file... -lpool [ library... ]
#include <pool.h>
const char *pool_dynamic_location(void);
const char *pool_static_location(void);
uint_t pool_version(uint_t ver);
int pool_get_status(int *state);
int pool_set_status(int state);
int pool_resource_type_list(const char **reslist,
uint_t *numres);
DESCRIPTION
The pool_dynamic_location() function returns the location used by the
pools framework to store the dynamic configuration. The dynamic config‐
uration refers to the live state of the running system, and is also re‐
ferred to as the "running" configuration.
The pool_static_location() function returns the location used by the
pools framework to store the default configuration file. This is the
default configuration used by the pools command line utilities. This
file is applied during system boot if the pools SMF service is enabled.
The pool_version() function can be used to inquire about the version
number of the library by specifying POOL_VER_NONE. The current (most
capable) version is POOL_VER_CURRENT. The user can set the version used
by the library by specifying the required version number. If this is
not possible, the version returned will be POOL_VER_NONE.
The pool_get_status() function retrieves the current state of the re‐
source pools service. If state is non-null, then on successful comple‐
tion the state of the pools service is stored in the location pointed
to by state. The resource pools service is also represented by the SMF
service svc:/system/pools:default.
If the resource pools service is POOL_ENABLED, this means that the de‐
fault pool configuration file /etc/pooladm.conf will be applied during
system boot if it exists. If the status is POOL_DISABLED, the pool con‐
figuration file will not be applied at system boot. In either case,
libpool(3LIB), pooladm(8), and poolcfg(8) may be used to manipulate
pools.
The pool_set_status() function modifies the current state of the re‐
source pools service. On successful completion the state of the re‐
source pools service is changed to match the value supplied in state.
Only two values are valid for state, POOL_DISABLED and POOL_ENABLED,
both of which are defined in <pool.h>.
The pool_resource_type_list() function enumerates the resource types
supported by the pools framework on this platform. If numres and
reslist are both non-null, reslist points to a buffer where a list of
resource types in the system is to be stored, and numres points to the
maximum number of resource types the buffer can hold. On successful
completion, the list of resource types up to the maximum buffer size is
stored in the buffer pointed to by reslist.
RETURN VALUES
The pool_dynamic_location() function returns the location used by the
pools framework to store the dynamic configuration.
The pool_static_location() function returns the location used by the
pools framework to store the default configuration.
The pool_version() function returns the version number of the library
or POOL_VER_NONE.
Upon successful completion, pool_get_status(), pool_set_status(), and
pool_resource_type_list() all return 0. Otherwise, −1 is returned and
pool_error(3POOL) returns the pool specific error.
ERRORS
No errors are defined for pool_dynamic_location(), pool_static_loca‐
tion(), and pool_version().
The pool_get_status() function will fail if:
POE_SYSTEM A system error occurred when accessing the pool service
state.
The pool_set_status() function will fail if:
POE_SYSTEM A system error occurred when modifying the kernel pool
state.
The pool_resource_type_list() function will fail if:
POE_BADPARAM The numres parameter was NULL.
EXAMPLES
Example 1 Get the static location used by the pools framework.
#include <sys/types.h>
#include <unistd.h>
#include <pool.h>
...
const char *location = pool_dynamic_location();
...
(void) fprintf(stderr, "pool dynamic location is %s\n",
location);
Example 2 Enable the resource pools service.
#include <stdio.h>
#include <pool.h>
...
if (pool_set_status(POOL_ENABLED) != 0) {
(void) fprintf(stderr, "The pools service could not be enabled %s\n"
pool_strerror(pool_error()));
exit(2);
}
...
