DESCRIPTION

23       After initialization, each configuration must have one or more
24       functions added to it. Adding a function involves calling its bind()
25       method to allocate resources such as interface and string identifiers
26       and endpoints.
27
28       This function returns the value of the function's bind, which is zero
29       for success else a negative errno value.
