Special data types

In addition to the traditional C-89 data types, the Vue language also accepts seven special data types.

String type
The string data type is a representation of string literals. Unlike in C, the string is a basic data type in Vue
List type
A variable of type list collects a set of integral type values. The list type is an abstract data type and you cannot use a list variable directly with the standard C unary or binary operators.
Associative array type
An associative array is a map or look-up table consisting of a collection of keys and their associated values. There is a one-to-one mapping between a set of keys and values. Associative arrays are supported by Perl, ksh93, and several other languages.
Timestamp data type
A variable of type probev_timestamp_t holds the return value from the timestamp ProbeVue function, which returns a timestamp in internal AIX® format.
File path data type
A variable of type path_t can be used to hold the value of __file->path (refer to __file built in for I/O probe manager) or function fd_path(). Only local or global variables of type path_t are supported. A variable of this type can also be the key or value in an associative Array.
MAC address data type
A variable of type mac_addr_t is used to hold the value of MAC address. The MAC address data type is an abstract data type and you cannot use it directly with standard C unary or binary operators.
IP address data type
This is an abstract data type and cannot be used directly with standard C unary or binary operators. Only local or global variables of type ip_addr_t are supported. A variable of this type can also be stored in an associate array either as a key or as a value.
net_info_t data type
The net_info_t variable is structure or composite variable that is used to hold the network four tuples (local and remote IP addresses and port numbers) information from the specific socket descriptor through the sockfd_netinfo Vue function.
