DESCRIPTION
A pool_value_t is an opaque type representing the typed value portion of a pool property. For a list of the types supported by a
pool_value_t, see pool_get_property(3POOL).
The pool_value_alloc() function allocates and returns an opaque container for a pool property value. The pool_value_free() function must be
called explicitly for allocated property values.
The pool_value_get_bool(), pool_value_get_double(), pool_value_get_int64(), pool_value_get_string(), and pool_value_get_uint64() functions
retrieve the value contained in the pool_value_t pointed to by value to the location pointed to by the second argument. If the type of the
value does not match that expected by the function, an error value is returned. The string retrieved by pool_value_get_string() is freed
by the library when the value is overwritten or pool_value_free() is called on the pool property value.
The pool_value_get_type() function returns the type of the data contained by a pool_value_t. If the value is unused then a type of
POC_INVAL is returned.
The pool_value_set_bool(), pool_value_set_double(), pool_value_set_int64(), pool_value_set_string(), and pool_value_set_uint64() functions
set the value and type of the property value to the provided values. The pool_value_set_string() function copies the string passed in and
returns -1 if the memory allocation fails.
Property values can optionally have names. These names are used to describe properties as name=value pairs in the various query functions
(see pool_query_resources(3POOL)).
A copy of the string passed to pool_value_set_name() is made by the library, and the value returned by pool_value_get_name() is freed when
the pool_value_t is deallocated or overwritten.
RETURN VALUES
Upon successful completion, pool_value_alloc() returns a pool property value with type initialized to PVC_INVAL. Otherwise, NULL is
returned and pool_error() returns the pool-specific error value.
Upon successful completion, pool_value_get_type() returns the type contained in the property value passed in as an argument. Otherwise,
POC_INVAL is returned and pool_error() returns the pool-specific error value.
Upon successful completion, pool_value_get_bool(), pool_value_get_double(), pool_value_get_int64(), pool_value_get_string(), and
pool_value_get_uint64() return 0. Otherwise -1 is returned and pool_error(3POOL) returns the pool-specific error value.
Upon successful completion, pool_value_set_string() and pool_value_set_name() return 0. If the memory allocation failed, -1 is returned and
pool_error() returns the pool-specific error value.
ERRORS
The pool_value_alloc() function will fail if:
POE_SYSTEM A system error has occurred. Check the system error code for more details.
The pool_value_get_bool(), pool_value_get_double(), pool_value_get_int64(), pool_value_get_string(), and pool_value_get_uint64() functions
will fail if:
POE_BADPARAM The supplied value does not match the type of the requested operation.
The pool_value_set_string() function will fail if:
POE_SYSTEM A system error has occurred. Check the system error code for more details.
The pool_value_set_name() function will fail if:
POE_SYSTEM A system error has occurred. Check the system error code for more details.
