The network selection Application Programming Interface (API)
consists of a set of network configuration database
One group of these library routines accesses only the
entries identified by the
environment variable; another group of routines accesses

file) that contains entries for
each network available to the system.
set by a user or the system administrator,
which contains an ordered list of network identifiers.
These network identifiers match the
field and are used as links to
the records in the netconfig file.
Applications should use the routines that access
These routines allow users to influence the selection of transports
used by the application.
If an application does not want
the user to influence its decision,
then the routines that access the
database directly should be used.
The netconfig file,
on which the network selection library routines depend,
is maintained by the system administrator.
environment variable is typically set or modified by
application programmers and users,
depending on the needs of their applications,
but it may also be set by the system administrator
in response to the needs of administrative applications.
