Library summary

Functions for Erlang term construction.

Description

This module provides functions for creating and manipulating Erlang terms.

An Erlang term is represented by a C structure of type ETERM. Applications should not reference any fields in this structure directly, as it can be changed in future releases to provide faster and more compact term storage. Instead, applications should use the macros and functions provided.

Each of the following macros takes a single ETERM pointer as an argument. The macros return a non-zero value if the test is true, otherwise 0.

ERL_IS_INTEGER(t)

True if t is an integer.
