/**
 * @file  gmp.c
 * @brief The Greenbone Vulnerability Manager GMP library.
 *
 * This file defines a Greenbone Management Protocol (GMP) library, for
 * implementing managers such as the Greenbone Vulnerability Manager
 * daemon.
 *
 * The library provides \ref process_gmp_client_input.
 * This function parses a given string of GMP XML and tracks and manipulates
 * tasks in reaction to the GMP commands in the string.
 */

/**
 * @internal
 * The GMP-"Processor" is always in a state (\ref client_state_t
 * \ref client_state ) and currently looking at the opening of a GMP element
 * (\ref gmp_xml_handle_start_element ), at the text of a GMP element
 * (\ref gmp_xml_handle_text ) or at the closing of a GMP element
 * (\ref gmp_xml_handle_end_element ).
 *
 * The state usually represents the current location of the parser within the
 * XML (GMP) tree.  There has to be one state for every GMP element.
 *
 * State transitions occur in the start and end element handler callbacks.
 *
 * Generally, the strategy is to wait until the closing of an element before
 * doing any action or sending a response.  Also, error cases are to be detected
 * in the end element handler.
 *
 * If data has to be stored, it goes to \ref command_data (_t) , which is a
 * union.
 * More specific incarnations of this union are e.g. \ref create_user_data (_t)
 * , where the data to create a new user is stored (until the end element of
 * that command is reached).
 *
 * For implementing new commands that have to store data (e.g. not
 * "\<help_extended/\>"), \ref command_data has to be freed and NULL'ed in case
 * of errors and the \ref current_state has to be reset.
 * It can then be assumed that it is NULL'ed at the start of every new
 * command element.  To implement a new start element handler, be sure to just
 * copy an existing case and keep its structure.
 *
 * Attributes are easier to implement than elements.
 * E.g.
 * @code
 * <key_value_pair key="k" value="v"/>
 * @endcode
 * is obviously easier to handle than
 * @code
 * <key><attribute name="k"/><value>v</value></key>
 * @endcode
 * .
 * For this reason the GET commands like GET_TASKS all use attributes only.
 *
 * However, for the other commands it is preferred to avoid attributes and use
 * the text of elements
 * instead, like in
 * @code
 * <key_value_pair><key>k</key><value>v</value></key_value_pair>
 * @endcode
 * .
 *
 * If new elements are built of multiple words, separate the words with an
 * underscore.
