Список параметров

conn_identifier

Connection identifier.

oid

OID of the instance that you want to read.

Name of the attribute that you want to read.

Возвращаемые значения

Content of the requested attribute, when process is successful; When attr is set with string data type, the result is returned as a string; when attr is set with array data type (0-based numerical array), then the result is returned in associative array. When attr is omitted, then all attributes are received in array form.
