/*
|
This module contains declarations of the legacy style EPANET API functions, with
|
version 2.2 updates, that apply only to single threaded applications. A second
|
set of thread safe API functions that allows one to run concurrent analyses on
|
multiple EPANET projects can be found in the epanet2_2.h header file. The two
|
APIs share the same function names and arguments with the difference being that
|
the thread safe functions use the prefix "EN_" and include an extra argument that
|
represents the EPANET project being analyzed. To avoid unneccesary repetition,
|
only the thread safe API functions have been documented. To see a description of
|
a legacy style API function declared here please refer to its complementary named
|
function in epanet2_2.h.
