NAME
pool_get_property, pool_put_property, pool_rm_property, pool_walk_properties - resource pool element property manipulation SYNOPSIS
cc [ flag... ] file... -lpool [ library... ] #include <pool.h> pool_value_class_t pool_get_property(pool_conf_t *conf, const pool_elem_t *elem, const char *name, pool_value_t *property); int pool_put_property(pool_conf_t *conf, pool_elem_t *elem, const char *name, const pool_value_t *value); int pool_rm_property(pool_conf_t *conf, pool_elem_t *elem, const char *name); int pool_walk_properties(pool_conf_t *conf, pool_elem_t *elem, void *arg, int (*callback)(pool_conf_t *, pool_elem_t *, const char *, pool_value_t *, void *)); DESCRIPTION
The various pool types are converted to the common pool element type (pool_elem_t) before property manipulation. A pool_value_t is an opaque type that contains a property value of one of the following types: POC_UINT unsigned 64-bit integer POC_INT signed 64-bit integer POC_DOUBLE signed double-precision floating point value POC_BOOL boolean value: 0 is false, non-zero is true POC_STRING null-terminated string of characters The conf argument for each function refers to the target configuration to which the operation applies. The pool_get_property() function attempts to retrieve the value of the named property from the element. If the property is not found or an error occurs, the value POC_INVAL is returned to indicate error. Otherwise the type of the value retrieved is returned. The pool_put_property() function attempts to set the named property on the element to the specified value. Attempting to set a property that does not currently exist on the element will cause the property with the given name and value to be created on the element and will not cause an error. An attempt to overwrite an existing property with a new property of a different type is an error. The pool_rm_property() function attempts to remove the named property from the element. If the property does not exist or is not remov- able, -1 is returned and pool_error(3POOL) reporst an error of POE_PUTPROP. The pool_walk_properties() function invokes callback on all properties defined for the given element. The callback is called with the ele- ment itself, the name of the property, the value of the property, and the caller-provided opaque argument. A number of special properties are reserved for internal use and cannot be set or removed. Attempting to do so will fail. These properties are documented on the libpool(3LIB) manual page. RETURN VALUES
Upon successful completion, pool_get_property() returns the type of the property. Otherwise it returns POC_INVAL and pool_error() returns the pool-specific error value. Upon successful completion, pool_put_property(), pool_rm_property(), and pool_walk_properties() return 0. Otherwise they return -1 and pool_error() returns the pool-specific error value. ERRORS
The pool_get_property() function will fail if: POE_BADPARAM The supplied configuration's status is not POF_VALID, the supplied conf does not contain the supplied elem, or the property is restricted and cannot be accessed by the library. POE_SYSTEM A system error has occurred. Check the system error code for more details. The pool_put_property() function will fail if: POE_BADPARAM The supplied configuration's status is not POF_VALID, the supplied conf does not contain the supplied elem, the prop- erty name is not in the correct format, or the property already exists and the supplied type does not match the exist- ing type. POE_SYSTEM A system error has occurred. Check the system error code for more details. POE_PUTPROP The property name is reserved by libpool and not available for use. POE_INVALID_CONF The configuration is invalid. The pool_rm_property() function will fail if: POE_BADPARAM The supplied configuration's status is not POF_VALID, the supplied conf does not contain the supplied elem, or the property is reserved by libpool and cannot be removed. POE_SYSTEM A system error has occurred. Check the system error code for more details. POE_PUTPROP The property name is reserved by libpool and not available for use. The pool_walk_properties() function will fail if: POE_BADPARAM The supplied configuration's status is not POF_VALID. POE_SYSTEM A system error has occurred. Check the system error code for more details. ATTRIBUTES
